MATLAB: I could not create graph using plot command, where is the fault

Question

Cp0=-.41;
M=0:.1:.9;
Cpcr1=(Cp0/sqrt(1-(M^2)));
plot(M,Cpcr1)

Answer 1

M is an array so you need to use ./ and .^ instead of / and ^.

Cp0=-.41;
M=0:.1:.9;
Cpcr1=(Cp0./sqrt(1-(M.^2)));
plot(M,Cpcr1, 'b*-', 'LineWidth', 2);
grid on;
