running Tisean from matlab

Hi

I just have a very simple code to make a demo of TISEAN in MATLAB It works with no error and the "status" returns zero. however, the output file is not made. Interestingly, if I simply write the same command in command prompt (cmd, windows XP), the output file is generated. Could you tell me what may be wrong here?

tiseanPath = 'C:\TISEAN3\bin\';

a = 1.4;

[status,result]=system([tiseanPath,'henon -B0.3 -A',num2str(a),' -l1000 -o ']);

Thanks very much in advance
