I would like to multiply multiple 4x4 matrices together but each element of each matrix is a variable, and so in MATLAB is a vector. I therefore want to perform matrix multiplication on the matrices but element by element multiplication of the vectors inside, is this pos...

In contrast to matrix operations, element-wise operations are confined to arrays of equal size; they are denoted with a point typed preceding the arithmetic operator, namely: .*element‐wisemultiplication;./element‐wiserightdivision;.\element‐wiseleftdivision;.^element‐wiseexponentiation. For ...
I got automatic offload running for MATLAB and was able to test matrix multiplication and some LAPACK functions running on the Phi. However, I was wondering if it was possible to run element-wise operations on the Phi, for example: A=rand(10000,10000); B=rand(10000,10000); C=A.*B; ...

I want to have the input of a slider as an element of the vector f, in order to perform a matrix multiplication Kfinv*f. However Matlab keeps showing me the message "Incorrect dimension for matrix multiplications". How can I fix this?
