smooth2a 1.0

Smooths 2D array data. Ignores NaN's.function matrixOut = smooth2a(matrixIn,Nr,Nc) This function smooths the data in matrixIn using a mean filter over arectangle of size (2*Nr+1)-by-(2*Nc+1). Basically, you end up replacingelement "i" by the mean of the rectange centered on "i". Any NaNelements are ignored in the averaging. If element "i" is a NaN, then itwill be preserved as NaN in the output. At the edges of the matrix,where you cannot build a full rectangle, as much of the rectangle thatfits on your matrix is used (similar to the default on Matlab's builtinfunction "smooth")."matrixIn": original matrix"Nr": number of points used to smooth rows"Nc": number of points to smooth columns. If not specified, Nc = Nr."matrixOut": smoothed version of original matrix%%%%%%%%%Explanation of screenshot:The left plot is a pcolor (shading interp, axis equal) of a "jagged" 906x1024 matrix. Note that the edges have NaN values (white coloring). On the right, pcolor of output of smooth2a, with Nr = Nc = 50. NaN's are preserved, but do not affect the smoothing of adjacent elements.
