HEPL FOR A FUNCTION

[CARMEN SANCHEZ]

Good morning:
 
I am using octave to resolve a matrix problem.
 
I have this matrix:
 
A=[-0,195966, -0,397014, -0,538551, -0,954502;                             
-0,021981,      0,387760,   -0,593141,   -0,240908;
-0,195130,      0,013832,   -0,686614,   -0,901565;
0,134872,      0,711619,   -0,339303,      0,440442];
 
Is there any octave function to reduce decimals to just only 2 decimals without erase them manually?
 
Best regards,
