I have rho (2991*1), data (2991*1), and I created theta = (0:0.5:90)*pi/180; to represent a quarter of a circle. I can mesh rho and theta together using meshgrid. but then I don't know how to use my data to be correlated to the mesh?

I have some data along a line in a Cartesian coordinate. I know I can transform the Cartesian into polar coordinates using cart2pol. I would like to know how could I create a grid to map a quarter circle with the data along the initial line (to have a top view)?
thank you

Maybe the FAQ???

What do you want out? An image (2D array)? A plot/graph?
All I can think of was a not very efficient method based on the FAQ. I hesitate to show it because it's not fast, efficient, or clever. Hopefully someone else will come up with a fast and clever method.
