Hello everyone,
Below is a code i am trying to write. When I run it, I get errors due to matrix dimensions. May I know how to solve such errors please,thanks.
function h = mtimes(u,v)
% Multiplication with matrix or scalar: `h = u*v`
if ~isa(u,'ADI') %u is a scalar/matrix
h = v;
h.val = u.*(h.val);
h.jac = ADI.mtimesJac(u, h.jac);
elseif ~isa(v,'ADI') %v is a scalar
h = mtimes(v,u);
else % special case where either u or v has single value
if numel(u.val) == 1
h = u;
h.val = times(u.val, v.val);
h.jac = ADI.timesJacUnit(u.val, v.val, u.jac, v.jac);
elseif numel(v.val) == 1
h = u;
h.val = times(u.val, v.val);
h.jac = ADI.timesJacUnit(v.val, u.val, v.jac, u.jac);
else
error('Operation not supported');
end
end
end
the errors are;
Error using .*
Matrix dimensions must agree.
Error in * (line 161)
h.val = u.*(h.val);

To keep the thread readable I moved the classdef to an attachment and edited your comment for you. Next time, please use the tools explained on this page to make your posts more readable.
Can you provide the code you are using to reproduce this error? (also, posting code in this forum sometimes removes blank lines, so the line numbers in your errors don't line up with the code anymore.

You have shadowed the internal function mtimes which is used when you use the * operator. Renaming your function should solve the issue.
