conversion from matlab to python of repmat [duplicate] Ask Question Asked 7 years, 8 months ago. The numpy equivalent of repmat(a, m, n) is tile(a, (m, n)). Matlab과 Python 간에는 차이가 없습니다. So when you translate to python function foo that calls repmat, you need to get repmat somewhere to get a working code. However, the doc " NumPy for MATLAB Users " only covers the case to duplicate a matrix in 2D, e.g., repmat(a, m, n) . For example, octave library contains over 100,000 lines of matlab code split over 1000 functions. Active 7 years, 8 months ago.

The number of times a is repeated along the first and second axes.. Returns (Numpy gives a 3d output array as you would expect - matlab for some reason gives 2d output - but the content is the same). 따라서 두 명령 repmat(M,m,n) % matlab np.tile(M,(m,n)) # python 는 랭크 2의 매트릭스 (이차원) 정말 동등하다. Do an Matlab call to Python, dump your OP2 results matrices using to hdf5 (using h5py) and load them into and load them Matlab. Repmat replicates and tiles an array. A significant part of what the user perceives as "matlab" or "octave" functionality is a huge library, written in matlab.

In MATLAB, I'd do something like Xm = X - repmat(max(X,[],2), 1, size(X,2)); For Python, I've been toying with variations of Xm = X - np.matlib.repmat(np.max(X,axis = 1), 1, len(X[0])) but to no avail! Thanks for your terrific work on this very-useful Python tool! Perfect sinc interpolation in Matlab and Python. Parameters a array_like. Mlabwrap is a high-level python to Matlab bridge that lets Matlab look like a normal python library. Related numpy.matlib.repmat¶ matlib.repmat (a, m, n) [source] ¶ Repeat a 0-D to 2-D array or matrix MxN times. Vectorizing code generally means to take code with looping constructs and re-code them to utilize Matlab's inherent ability to work with arrays. Perfect sinc interpolation in Matlab and Python. Dependencies and Setup¶. The array or matrix to be repeated. It is a powerful and commonly used function as it can be used to "vectorize" code. This question already has answers here: What is the equivalent of MATLAB's repmat in NumPy (7 answers) Closed 7 years ago. In the Julia, we assume you are using v1.0.2 or later with Compat v1.3.0 or later and have run using LinearAlgebra, Statistics, Compat A while ago, I had to translate a MATLAB script into Python and it had a lot of repmat() . m, n int. George A. Blaha, Senior Systems Engineer, Raytheon Integrated Defense Systems mlab is a repackaging effort to make things up-to-date. Use the Matlab-Python Interface. Matlab: >> repmat([1;1],[1,1,1]) ans = 1 1 Python: In the Python code we assume that you have already run import numpy as np. Repmat without using Repmat. It’s recommended that you don’t use scipy’s MAT reader as it seems to be buggy, not to mention that hdf5 has replaced the MAT format in Matlab. 매트릭스가 이미 가지고있는 치수에 따라 입력 행렬을 조작해야합니다. This works with multiple dimensions and gives a similar result to matlab. repmat is a MATLAB function. ... % sincM = repmat( u, 1, length(s) ) - repmat( s', length(u), 1 ); % % So that the matrix would be longer than it is wide.
