Width
G3 = gauss3D(sz_X, sz_Y, sz_Z, a, prec);returns a 3 dimensional matrix being a gaussian bell curve where the width in the (x/y/z)-dimension is proportional to 1/a(1), 1/a(2) and 1/a(3), respectively. "prec" is the data precision.Default is a=[2.5 2.5 2.5] and prec='double'Examples:Cubic-shaped...
