Error in mmwave_3d_angle (line 234)

surf(yvalue, xvalue,abs(Xpow) ,'EdgeColor','none');

Size of xvalue and yvalue is in the matrix of 100X256, but the size of Xpow is 128X256

Answer 1

[Sulaymon Eshkabilov]

Check the sizes of these variables:

size(yvalue)

size(xvalue)

size(abs(Xpow))

See e.g.:

x = -10:.2:10;
y = -pi:.1:pi;
[Xvalues, Yvalues]=meshgrid(x,y);
Z = exp(sin(Xvalues))+exp(cos(Yvalues));
surf(Yvalues, Xvalues,Z)   % Correct entries

Xt = Xvalues.';
surfc(Yvalues, Xt, Z)    % size mismatch
