Error using * Inner matrix dimensions must agree.

Não consigo enteder porque aparece esse erro. Só que esse progrma não tem matriz.

wd = wn*(sqrt(1-eta^2));
o =  atan((c*w)/k-(m*(w^2)));

[Walter Roberson]

Change all of your * to .* and all of your / to ./ and all of your ^ to .^

In MATLAB, * is algebraic matrix multiplication ("inner product"), and / is matrix division (A/B is much like A*pinv(B)), and ^ is matrix exponential, repeated algebraic matrix multiplication.
