One technique is to index into the array with ones in the dimension to replicate. Out0 = np.convolve(a,np. repmat uses a variety of techniques for replicating an array, depending on the details of whats being replicated. # as in the original MATLAB implementation # WSZ: smoothing window size needs, which must be odd number, # a: NumPy 1-D array containing the data to be smoothed Thus, we would have an implementation to handle generic window sizes, like so - def smooth(a,WSZ): Then, simply append the special case treated values for the boundary elems. So, to replicate the same implementation on NumPy/Python, we can use NumPy's 1D convolution for getting sliding windowed summations and divide them by the window length to give us the average results. example matrix int8(zeros(100)) Repmat function is used to create a single. The number of times a is repeated along the first and second axes. matlab split matrix into blocks In this example I have a column matrix with. Defaults to square if dimension argument. Value Returns matrix with value A tiled to the number of dimensions specified. Must be numeric, logical, complex or character. For example, repmat(1 2 3 4,2,3) returns a 4-by-6 matrix. repmat: MATLAB repmat function Description Replicate and tile a matrix. When A has N dimensions, the size of B is size(A).r1.rN. Yy(3) = (y(1) + y(2) + y(3) + y(4) + y(5))/5 B repmat(A,r1.,rN) specifies a list of scalars, r1.,rN, that describes how copies of A are arranged in each dimension. Introduction to Matlab stem() Stem() method in MATLAB is a type of plotting method to represent any type of data in a discrete form.

The first few elements of yy are given by As per the linked docs, those boundary cases are computed with these formulae - yy = smooth(y) smooths the data in the column vector y.

From A First Course in Machine Learning, Chapter 5.MATLAB's smoooth func is basically same as averaging across sliding windows of length 5, except the way it treats the 2 elems at either ends. I found julias repeat function run very slowly than matlabs repmat and python too,here is my code of julia and matlab for a test of two functions.
