[scilab-Users] vector elementwise division 1./[1 2 3 4]

[Antoine ELIAS]

Hi Bagvian,

Yes it's strange but "normal' :D
Scilab's parser tries to interpret "1." and after "/V1"
So for Scilab you try to divide 1.0 ( floating point value ) by V1 ( not 
element wise )
To be sure Scilab use "./" operator, add spaces around operator like "1 
./ V1"
