The code generator does not specialize multiplication by pure imaginary numbers—it does not eliminate calculations with the zero real part. For example, (Inf + 1i)*1i = (Inf*0 – 1*1) + (Inf*1 + 1*0)i = NaN + Infi. Matrix Multiplication Operation to MathWorks BLAS Code Replacement. You can develop a code replacement library for floating-point matrix/matrix and matrix/vector multiplication operations with the multiplication functions dgemm and dgemv defined in the MathWorks BLAS library.

3D Matrix Multiplication. Learn more about matrix . Hi I have created two large matrices of which I have reshaped to create the following: For matrix multiplication, e.g. A*B, the number of columns in A must equal the number of rows in B. For element-by-element multiplication, e.g. A.*B, the size and shape of both A and B must be exactly the same.
