Transform a 3d volume by using an affine transformation matrix 1.0
This function transforms volume 'old_im' by means of affine transformation matrix 'M'. The output volume can be sub- and oversampled. The function makes use of interp3, so 'nearest', 'linear', 'spline', 'cubic' and fast ( * ) interpolation is...

decimation matrix 1.0
This function gives the decimation matrix which after post mulitpling it with the given signal gives the downsampled version of the original signal...D = decimmtx(x,N)decimates the given signal by a factor of N.[D,y] = decimmtx(x,N)gives D as well...

Fast function to save a matrix 1.0
write_matrix_bin(f,m) saves the matrix "m" in a binaryfile "f". write_matrix_bin is a lot faster than the built in function save(), andtakes up much less diskspace than the old "save -v6" which doesn't use compression.write_matrix_bin also...
