A multidimensional array in MATLAB® is an array with more than two dimensions. In a matrix, the two dimensions are represented by rows and columns. Each element is defined by two subscripts, the row index and the column index. Multidimensional arrays are an extension of 2-D matrices and ...

MATLAB Online에서 열기 First convert the data to a 2D matrix M = rand(6, 6, 100); M_new = reshape(permute(M, [2 1 3]), 6, []).'; and then you can use xlswrite(). writematrix() can also handle multidimensional arrays. ...

To extend the rows, columns, or pages of an array, use similar assignment statements. The dimensions of arrays on the right side and the left side of the assignment must be the same. ExtendAinto a 3-by-3-by-3-by-2, four-dimensional array. In the first assignment, MATLAB padsAto fill...
To copy the input to a new matrix, modify it as a Fortran 3D variable, and return the result back to MATLAB you could do this: ThemeCopy useMatlabAPImx real*8, pointer:: X(:,:,:) plhs(1) = mxDuplicateArray(prhs(1))! Copies the data ...
