In this case I think permute, as proposed, would do exactly what a user expects: return the specified permutation of the array. Does this name conflict with any existing functions?.Would a user expect a function with this name to do what it does?.

When considering new names I think natural questions are: It plans to implement swapaxes as an alternative transposition mechanism, so swapaxes and permute would work on both PyTorch tensors and NumPy-like arrays (and make PyTorch tensors more NumPy-like). PyTorch uses transpose for transpositions and permute for permutations.

It would be helpful to provide library writers a mechanism to permute both NumPy-like arrays and PyTorch tensors.

It is the correct mathematical name for the operation.

This issue proposes a new function, permute, which is equivalent to transpose except it requires the permutation be specified. A 'transposition,' however, is typically a swap of two elements, like what swapaxes does. Reshape & Permute are eating too much memory which seems to get never. Reshape function is used to give a new shape to the array with a specified number of rows and columns.Today in NumPy there's transpose, which 'reverses or permutes' an array's axes. The reshaped array should be compatible with the original array. It is used in both Python and Matlab to execute various operations in the array. After reshaping the array, it adjusts the memory allocation accordingly. Sorting the data in an array is also a valuable tool, and MATLAB offers a number of approaches. For example, the sort function sorts the elements of each row or column of a matrix separately in ascending or descending order. Create a matrix A and sort each column of A in ascending order. When you use to automatically calculate a dimension size, the dimensions that you do explicitly specify must divide evenly into the number of elements in the input matrix, numel(A). Beyond the second dimension, the output, B, does not reflect trailing dimensions with a size of 1. r1 randperm (8,4) r1 1×4 6 4 7 3 Generate another random permutation of four unique integers. For example, reshape(A,3,2,1,1) produces a 3-by-2 matrix. Permute a Selection of Integers Try This Example Copy Command Generate a random permutation of four unique integers (without repeating elements) selected randomly from the integers 1 to 8. matlab permuteī = permute(A,dimorder) rearranges the dimensions of an array in the order specified by the vector dimorder. For example, permute(A,) switches the row and column dimensions of a matrix A. P = perms(v) returns a matrix containing all permutations of the elements of vector v in reverse lexicographic order. Each row of P contains a different permutation of the n elements in v. Matrix P has the same data type as v, and it has n! rows and n columns. Newarray = permute(sysarray,order) rearranges the array dimensions of a model array so that the dimensions are in the specified order. The input and output dimensions of the model array are not counted as array dimensions for this operation. Rearrange the dimensions of a multidimensional array. B = permute(A,order) rearranges the dimensions of A so that they are in the order specified by the vector order. B has the same values of A but the order of the subscripts needed to access any particular element is rearranged as specified by order. MATLAB includes a function called permute(), which is a generalization of the transpose function but for ND arrays. Permute() takes in an ND-array and the desired array order and then returns the rearranged data. The syntax looks this: newArray = permute( oldArray, ). Permute does a permutation of the dimensions of an array, not of its elements, as one may expect from its name. Thus, permute(A,) flips dimension 2 (the columns) of array A with dimension 1 (the rows) of array A, which is equivalent to a transpose (A'). This MATLAB function returns a row vector containing a random permutation of the integers from 1 to n without repeating elements.

Mat = vec2mat (vec,matcol) converts the vector vec into a matrix with matcol columns, creating one row at a time. If the length of vec is not a multiple of matcol, then extra zeros are placed in the last row of mat. The matrix mat has ceil (length (vec)/matcol) rows.
