I want to be able to see a "side-view" (or volumetric representation) of these images which will show the surface that a particular line "carves out" in its movement across the images. The data increases along the rows, I mean, each column has 32 points that are the plot of one curve, so I plot each time one curve, which would correspond to a value of theta and phi. Matlab stores array dimensions and array number rows and columns. Directly showing the path of movement a "line" carves out is hard with raster data, because Matlab won't know which "moved" pixels in two subsequent images are associated with each other. Multidimensional arrays are an extension of 2-D matrices and use additional subscripts for indexing. The array is then 32x360x360 (32xthetaxphi), so how can I put a title that changes first the theta going from 0 to 360 and every time it reaches 360, the phi increases 1 and the theta starts again. I would suggest to you that a double nested loop would be clearer code. You could also plot it by using patch() to draw each individual "on" pixel as a polygon in 3-D space.
