In matlab the .* operator is an element-by-element multiplication.The matrices must be the same dimensions.If you intended a true matrix multiplication then just use the * operator, and the matrices must have the correct relative dimensions as noted in the Wikipedia article quoted by Sergey.

Sql query vs stored procedure in source task of DFT in SSIS

25 Apr 2016 by dinesh42

I have some SSIS packages wherein inside the DFTs the source task contains a sql query to fetch data from a database and then processed and then stored to another table.But the problem is DFT is taking so much time to pull the rows into the buffer for processing, hence the execution times...

Multiply two matrix with different dim in matlab

18 May 2016 by amir.nazarizadeh

I downloaded dftfilt that a function for image filtering in matlab! but it has some problem the following is code of that: function g = dftfilt(f, H) F = fft2(f, size(H, 1), size(H, 2)); g = real(ifft2(H.*F)); g = g(1:size(f,1),1:size(f,2));but in line 3 gives me an...

Multiply two matrix with different dim in matlab

18 May 2016 by Sergey Alexandrovich Kryukov

Multiplication of matrices of arbitrary dimension is not defined. The height of one must match the width of another one.Matrix multiplication is extremely simple (in contrast to division/inversion). Please see, for example:Matrix multiplication — Wikipedia, the free encyclopedia[^].Pay...
