Error using surf
Data dimensions must agree.
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

Ran in:
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
Error using surf
Data dimensions must agree.

Error in surfc (line 54)
hs = surf(cax, args{:});
