Para error at END

now calculate v_phase for each level of current ii = 1:21

v_phase (ii)= sqrt(e_a^2 - (x_s * i_a(ii) * cod(theta))^2) - (x_s * i_a(ii) * sin(theta));
end

this of above says "Parse error at END: usage might be invalid MATLAB syntax"

Answer 1

The loop has for missing at the beginning should be

for ii = 1:21

cos() not cod().
