Sparse Support for MATLAB Coder

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

Hi,

I think it does and it is disabled by default:

Where do i have to set this "sparse=true"?? Icannot find a setting.

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)));
