Hello
I want to create an array in Simulink based on two constants. Like using "linspace(1,1,10)" in Matlab, but from two constant blocks of magnitude "1" and "10".
Thanks in Advance

You can use Matlab function block

I tried, but I can't write:
function y = fcn(u)
y=linspace(1,u,u)
end;
"u" is not a parameter input, it is a constant input, that can vary.
Thanks

Read this http://www.mathworks.com/help/fixedpoint/ref/coder.nullcopy.html
function y = fcn(u)
%#codegen
coder.extrinsic('linspace')
y = coder.nullcopy(zeros(1,numel(u)));
y =linspace(1,u, u)
Don't forget to declare the output y (type edit data in the editor of your function) as variable size.
