Why do I receive a segmentation violation when I pass in an INT16/INT32 datatype into the RESAMPLE function in the Signal Processing Toolbox?

When I type

z = int32(50*rand(10000,1));

zrs = resample(z, 10, 625);

I receive the following segmenation violation:

This bug has been fixed in Release 14 Service Pack 2 (R14SP2). For previous releases, please read below for any possible workarounds:

The RESAMPLE function in the Signal Processing Toolbox only handles double datatype variables.

To work around this issue, try converting the input signal to a double datatype using the DOUBLE function. For example,

Instead of

zrs = resample(z, 10, 625);

try

z = double(z);

zrs = resample(z, 10, 625);
