np.tile Python numpy 下的 np.tile有些类似于 matlab 中的 repmat函数。不需要 axis 关键字参数，仅通过第二个参数便可指定在各个轴上的复制倍数。 So when you translate to python function foo that calls repmat, you need to get repmat somewhere to get a working code. Repmat without using Repmat. Active 7 years, 8 months ago. ... % sincM = repmat( u, 1, length(s) ) - repmat( s', length(u), 1 ); % % So that the matrix would be longer than it is wide. 따라서 두 명령 repmat(M,m,n) % matlab np.tile(M,(m,n)) # python 는 랭크 2의 매트릭스 (이차원) 정말 동등하다. It is a powerful and commonly used function as it can be used to "vectorize" code. 我想使用NumPy执行相当于以下MATLAB代码：repmat([1; 1]，[1 1 1])。我该如何做到这一点？ 这里是一个更好的(官方) NumPy for Matlab Users链接 – 恐怕mathesaurus一个是相当过时的。 repmat(a，m，n)的numpy等价于tile(a, (m, n))。 这与多维度工作，并给出类似的结果matlab。 (Numpy给出一个3d输出数 Matlab과 Python 간에는 차이가 없습니다. Matlab: >> repmat([1;1],[1,1,1]) ans = 1 1 Python: This works with multiple dimensions and gives a similar result to matlab. The number of times a is repeated along the first and second axes.. Returns In the Python code we assume that you have already run import numpy as np. Repmat replicates and tiles an array. Mlabwrap is a high-level python to Matlab bridge that lets Matlab look like a normal python library. m, n int. For a given matrix, I'm subtracting the maximum of each row from the row. 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 Use the Matlab-Python Interface. Perfect sinc interpolation in Matlab and Python. Thanks for your terrific work on this very-useful Python tool! (Numpy gives a 3d output array as you would expect - matlab for some reason gives 2d output - but the content is the same). Viewed 1k times -1. 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! However, the doc " NumPy for MATLAB Users " only covers the case to duplicate a matrix in 2D, e.g., repmat(a, m, n) . This question already has answers here: What is the equivalent of MATLAB's repmat in NumPy (7 answers) Closed 7 years ago. Perfect sinc interpolation in Matlab and Python. Related Do an Matlab call to Python, dump your OP2 results matrices using to hdf5 (using h5py) and load them into and load them Matlab. 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. Parameters a array_like. 매트릭스가 이미 가지고있는 치수에 따라 입력 행렬을 조작해야합니다. GitHub Gist: instantly share code, notes, and snippets. numpy.matlib.repmat¶ matlib.repmat (a, m, n) [source] ¶ Repeat a 0-D to 2-D array or matrix MxN times. For example, octave library contains over 100,000 lines of matlab code split over 1000 functions. repmat is a MATLAB function. The array or matrix to be repeated. A while ago, I had to translate a MATLAB script into Python and it had a lot of repmat() . Vectorizing code generally means to take code with looping constructs and re-code them to utilize Matlab's inherent ability to work with arrays. The numpy equivalent of repmat(a, m, n) is tile(a, (m, n)). George A. Blaha, Senior Systems Engineer, Raytheon Integrated Defense Systems mlab is a repackaging effort to make things up-to-date. Dependencies and Setup¶. GitHub Gist: instantly share code, notes, and snippets. conversion from matlab to python of repmat [duplicate] Ask Question Asked 7 years, 8 months ago.
