Interpolate matrix (1300X20000) to a smaller matrix (62X119)

Hi all, is there a way to resize a matrix with interpolate command? i have bunch of values in big matrix and i want to interpolate those values to smaller matrix.

Best regards, Evyatar.

Do you wish to interpolate, or do you really want to do some form of decimation, downsampling? There are different routines one would use, with different results and different goals.

Hi John, I wish to interpolate, does the function 'scatteredInterpolant' is good for me?

Best regards, Evyatar.

If it is a rectangular grid then griddedInterpolant .

You might be able to use the interp2 function.

By the way, interp2 calls griddedInterpolant internally.
