Simulink does not have enough information to determine output sizes for this block. If you think the errors below are inaccurate, try specifying types
function y = fcn(R1,R2,w,f,l)
y = (1-(R1/R2)^w*exp(1)^(-f*l/R2));

Make sure your function is correct. Manually give a numerical example value to obtain the resulting y value.
In the MATLAB Function block editor, click "Edit data" and specify the size of y, for example, 1, or [2,3] or whatever.
