I am trying to graph this using the M array as input values
%For graph
x = 0 : 0.1 : 2;
y = 0.7*(x.^2)*(1+0.2*(x.^2))^-3.5
figure(1)
plot(x,y)
grid
This error is returned:
Error using ^ (line 51)
Incorrect dimensions for raising a matrix to a power. Check that the matrix is square and the power
is a scalar. To perform elementwise matrix powers, use '.^'.
Error in aero (line 3)
y = 0.7*(x.^2)*(1+0.2*(x.^2))^-3.5
It was also not working trying to retrive N's values and not graphing. What am I doing wrong?
