Does the MATLAB Coder support sparse Matrices created for example with the sparse() function? Something like
A = sparse(zeros(4,4));
A(3,3) = 1.0;
Thanks in advance

Use the syntax
t=coder.newtype(numeric_class, sz, variable_dims, Name, Value)
with Name being 'sparse' and Value being true:
t=coder.newtype(numeric_class, sz, variable_dims, 'sparse', true)

Hello and thank you for your answer.
Unfortunately it does not work. "coder.newtype" is not a recognized keyword.
I am trying to translate this:
A = sparse(zeros(p,2*p));
B = sparse(zeros(k+p,2*(k+p)));
