savematfile filename var1 var2 ...



character string containing the path of the file (needed)


data format to use


binary MAT-file (default)


8-bit ASCII format

"-ascii" "-double"

16-bit ASCII format

"-ascii" "-tabs"

delimits with tabs

"-ascii" "-double" "-tabs"

var1, var2

character strings containing the name of the variables to load (only for binary files)

"-struct" "s"

saves all fields of the scalar structure s as individual variables within the file filename.

"-struct" "s" "f1" "f2"

saves as individual variables only those structure fields specified (s.f1, s.f2, ...).


saves variables in a Matlab MAT-file from Scilab. The Scilab data types are converted into the Matlab equivalents.


A = rand(10,10);
B = sprand(100,100,0.1);
