savematfile
saves some Scilab variables in a Matlab MAT-file (binary or ASCII)
Syntax
savematfile('filename') savematfile('filename', varnames, ...) savematfile('filename', 'var1', 'var2', ...) savematfile filename var1 var2 ... savematfile('filename', '-struct', 's') savematfile('filename', '-struct', 's', 'f1', 'f2', ...) savematfile(..., format)
Arguments
- filename
character string containing the path+name of the file
- varnames
vector of the names (text) of variables to save, like
["var1" "var2"..]
.- "var1", "var2"...
character strings being the names of the variables to save.
- format
data format to use
"-mat" : binary MAT-file (default) "-v4" : A format that MATLAB Version 4 can open "-v6" : A format that MATLAB Version 6 and earlier can open "-v7" : A format that MATLAB Version 7 and earlier can open (default) "-v7.3" : A format that MATLAB Version 7.3 and earlier can open "-ascii" : 8-bit ASCII format "-ascii" "-double" : 16-bit ASCII format "-ascii" "-tabs" : delimits with tabs "-ascii" "-double" "-tabs" : 16-digit ASCII format, tab delimited - "-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, ...).
Description
Saves some Scilab variables in a Matlab MAT-file. The names of chosen variables may be provided as distinct input arguments, or through a vector of names. By default, all variables existing in the workspace are saved. The Scilab data types are converted into the Matlab equivalents.

Data type | v4 | v6 | v7 | v7.3 | ASCII | Comments |
---|---|---|---|---|---|---|
boolean | x | bug | bug | bug | x | Bug 15568 |
integer | x | X | X | X | no | int8 are stored as uint8 if they are all > 0, or as int16 otherwise. |
real | x | X | X | X | x | |
complex | x | X | X | X | x | ASCII: imaginary part ignored. |
sparse | x | x | x | x | x | Octave 4.4 loads correctly any real or complex sparse array saved from Scilab 6.0. |
boolean sparse | x | no | no | no | x | v4: Saved as sparse decimal 0|1. Well read from Octave 4.4 |
Text | x | ? | v4: Any array is saved as a column of texts right-padded with spaces to all have the same lengths. | |||
struct | no | x | X | no | ||
cell | no | X | X | X | no | Must not contain components of unsupported type or yielding errors/crashs |
