Why I got this error message when I run correlation analysis?

I got error message below, when I ran correlation analysis. Could someone tell me why I got this error message? Thanks a lot!

BLAS loading error:
  Error in cov (line 156)
  c = (xc' * xc) ./ denom;
  Error in corrcoef>correl (line 203)
  r = cov(x);
  Error in corrcoef (line 86)
     r = correl(x);

Not I, sorry. Looks like an internal error in the BLAS library routines, maybe; never seen that error message before.

Post a sample that reproduces the problem so folks here can try it; which version may be significant.

Can you succeed with corrcoef on any input? What about the example in the doc's?

Which version of MATLAB are you using? Which operating system are you using? Which exact CPU do you have?
