using "eval" function is quite slow


In addition to solutions already provided, you may use*strtod()*. It is 
made for that.

2013-03-05 Thread Antoine ELIAS 
You can use msscanf function too
http://help.scilab.org/docs/5.4.0/en_US/mfscanf.html

sample :

//your data
dataIn = string(rand(500,500));
typeof(dataIn)
size(dataIn)

//convert to double
tic();
dataOut = matrix(msscanf(-1, dataIn, "%f"), size(dataIn));
disp("convertion time : " + string(toc()));
typeof(dataOut)
size(dataOut)
