The complete side-by-side reference for converting MATLAB operations to Python. Array creation, math, linear algebra, indexing, plotting — all in one page.
Read →7 MATLAB-to-Python Gotchas That Silently Break Your Code
The differences between MATLAB and Python that produce code that runs without errors but gives wrong results. Reshape ordering, 1-based indexing, transpose semantics, and more.
Read →MATLAB 1-Indexed to Python 0-Indexed: The Complete Migration Guide
The single biggest source of bugs when converting MATLAB to Python. Every indexing pattern, every gotcha, every pattern for the `end` keyword — with copy-paste conversions.
Read →Convert MATLAB for Loops to Python: 12 Patterns and Their Pitfalls
Every common MATLAB for-loop pattern translated to Python — with the bugs to watch for in each. Covers range loops, reverse iteration, cell iteration, nested loops, and vectorization.
Read →MATLAB plot() to matplotlib: Side-by-Side Reference with Every Option
Convert MATLAB plotting code to matplotlib line by line. Covers plot, subplot, legends, labels, line styles, colorbars, 3D plots, and the differences that catch engineers off guard.
Read →MATLAB Signal Processing Toolbox to SciPy: Complete Function Reference
Every MATLAB Signal Processing Toolbox function mapped to its scipy.signal equivalent. Filter design, spectral analysis, convolution, transforms — with the gotchas that cause silent bugs.
Read →MATLAB findpeaks to Python: scipy.signal.find_peaks
Convert MATLAB findpeaks to Python with scipy.signal.find_peaks. Maps MinPeakHeight, MinPeakDistance, and prominence, plus the 0-based location gotcha and when results differ from MATLAB.
Read →MATLAB fft to Python: np.fft.fft, normalization, and fftshift
Convert MATLAB fft to Python with numpy.fft. Covers the normalization myth, the frequency axis with fftfreq, fftshift for centering, and rfft for real signals.
Read →MATLAB reshape to Python: the order='F' column-major gotcha
Convert MATLAB reshape to NumPy. MATLAB is column-major and NumPy is row-major, so reshape(A,m,n) needs order='F' to match. The same applies to A(:) flattening.
Read →MATLAB interp1 to Python: np.interp and scipy interp1d
Convert MATLAB interp1 to Python. Use np.interp for linear (mind the argument order) and scipy.interpolate.interp1d for spline/cubic, plus how to match MATLAB's extrapolation.
Read →MATLAB arrayfun to Python: vectorize, comprehensions, np.vectorize
Convert MATLAB arrayfun to Python. Most of the time you do not need it — NumPy vectorizes natively. When you do, use a list comprehension or np.vectorize, and mind UniformOutput.
Read →MATLAB cellfun to Python: list comprehensions over cell arrays
Convert MATLAB cellfun to Python. A cell array becomes a list, and cellfun becomes a list comprehension. Handles UniformOutput and the common string/length cases.
Read →MATLAB repmat to Python: np.tile and broadcasting
Convert MATLAB repmat to NumPy. repmat(A,m,n) maps to np.tile(A,(m,n)), but broadcasting is often the better, copy-free alternative. Covers the dimension differences.
Read →MATLAB sortrows to Python: np.lexsort, descending, and the index
Convert MATLAB sortrows to NumPy with np.lexsort. Covers sorting by a column, descending order, the [sorted, idx] index output, and the pandas alternative.
Read →MATLAB sprintf and num2str to Python: f-strings and str()
Convert MATLAB sprintf and num2str to Python. Map the % format specifiers to f-strings, handle num2str precision, and format arrays with the right Python idiom.
Read →MATLAB bsxfun to Python: NumPy broadcasting
Convert MATLAB bsxfun to Python. NumPy broadcasts element-wise operations natively, so bsxfun(@plus, A, b) becomes simply A + b. Includes the operator-handle mapping.
Read →MATLAB regexprep to Python: re.sub, arg order, and backreferences
Convert MATLAB regexprep to Python re.sub. Mind the reversed argument order, use raw strings for patterns, and translate $1 backreferences to \1. Plus regexp to re.findall.
Read →MATLAB accumarray to Python: np.bincount, np.add.at, pandas groupby
Convert MATLAB accumarray to Python. Use np.bincount with weights for sums (mind the 1-based subscripts), np.add.at for in-place accumulation, and pandas groupby for other reducers.
Read →MATLAB Image Processing Toolbox to Python: Complete scikit-image Guide
Convert MATLAB Image Processing Toolbox functions to Python. imresize, imfilter, edge detection, morphology — mapped to scikit-image and OpenCV with working code.
Read →MATLAB ode45 to Python: Solving ODEs with scipy.integrate
Replace MATLAB ode45, ode23, and ode15s with scipy.integrate.solve_ivp. Step-by-step conversion with working examples for IVPs, events, and stiff systems.
Read →MATLAB Cell Arrays in Python: Lists, Dicts, and NumPy Object Arrays
Cell arrays are MATLAB's heterogeneous container. In Python use lists, dicts, or NumPy object arrays. Learn which to use and how to convert your existing code.
Read →MATLAB struct to Python: dicts, dataclasses, and named tuples
Convert MATLAB struct and struct arrays to Python. When to use dict, when to use dataclass, and how to handle nested structs and dynamic field names.
Read →MATLAB vs Python in 2026: An Honest Comparison for Engineers
Where MATLAB is still better, where Python has caught up, and why the economics have shifted permanently.
Read →MATLAB License Cost in 2026: What Engineering Teams Are Actually Paying
MathWorks discontinued perpetual Home and Student licenses in January 2026 and pushes new buyers toward annual subscriptions. Here is what MATLAB actually costs per seat, per toolbox, and per team — and what switching to Python saves.
Read →Why We Built a Deterministic MATLAB-to-Python Converter (And Why It Doesn't Promise 100%)
MathWorks discontinued perpetual Home and Student licenses and pushes new buyers toward subscriptions. Every existing converter is dead or AI-based. We built the tool we wished existed — one that tells you what it can't do instead of guessing wrong.
Read →MATLAB to Python Converters in 2026: What Actually Works
An honest review of every MATLAB-to-Python converter available today — SMOP, LiberMate, OMPC, Mat2py, CodeConvert.ai, and ChatGPT. Most are dead or abandoned. Here is what is left.
Read →We Ran the Same MATLAB File Through an AI Converter and a Deterministic One. Here's What Happened.
A real head-to-head comparison: CodeConvert.ai silently dropped 30% of the code. Our deterministic converter kept everything and flagged what needed review.
Read →What Automated MATLAB-to-Python Conversion Actually Saves You (And What It Can't Do)
An honest look at what a deterministic converter handles, what still needs manual work, and why 85% automation plus clear flagging beats 100% with silent errors.
