Plot a surface with cross-section matrix

Good day,
I am looking on how to create a 3D surface directly on matlab (to be converted to igs and exported to Fluent). Currently I have a portion of a missile-like shape and I have the crossections stored in a matrix. The matrix size for the angular values is 576x640, meaning there are 576 cross-sections and 640 points per cross-section. The radial values are stored in a matrix of equal size. The distance vector, or the one that dictates how far is one crossection from the other is of size 1x576. (one value per cross-section). I cannot share the code due to its lenght but hopefully my issue could be explained properly.
I currently need to make a surface out of these matrices, preferably a surface that can later be generated on Ansys or can be exported to Solidworks. Help is much appreciated.

Did you end up finding an appropriate answer? I'm having the same issue but with x-y data and not radial

theta = your_angle
r = your_radial
z = your_z
% wrap around to close the azimuthal patch
theta = theta(:,[1:end 1]);
r = r(:,[1:end 1]);
x = r.*cos(theta);
y = r.*sin(theta);
z = repmat(z(:),1,size(x,2));
surf(x,y,z)

The coordinates are not polar.
