I have three matrices named in the cell array below. A function is used to calculate the upper triangular matrix of these three matrices. To do this i need to find the infinity norm of the matrices e.g. mu = norm(U, inf) but i get an error when running the code as it says U must be single or double. How do i find the infinity norm of a cell array? also tried to use vecnorm this also produced the same error.
mats={mat4, mat5, mat6};
nmats=length(ec15ess_mats);

I’m not sure what you want to do.
Try this:
mats = {rand(4), rand(5), rand(3)};
mu_mats = cellfun(@(x)norm(x,Inf), mats);
Experiment to get the result you want.
