Matlab matrices through Version 5 are supported on the following platforms:
Macintosh
Windows & OS/2
Unix HP/Sun/IBM
Matlab datasets for version 7+ are also supported.
Standard extension: mat
Reading Matlab Files
Stat/Transfer will automatically recognize an input file's platform of origin on input.
Matlab does not write variable names into the file. Therefore Stat/Transfer makes up a variable name for each column, 'coln', which consists of the string 'col' plus the number of the column.
All values in a given matrix are of a single type, usually double precision, although particularly large matrices may be written out by Matlab in integer format, when this is possible.
Strings are not supported in Matlab files.
Stat/Transfer does not read complex matrices.
Writing Matlab Files
On output, Stat/Transfer writes matrices that can be read by any version of Matlab. Datasets can be read on any version higher than seven.
Stat/Transfer always writes Matlab files in double precision.
Stat/Transfer does not write complex matrices.
Missing Data
Matlab supports missing values.
Output Variable Types
The output variable type that results from each target variable type is given in the following table:
Target Type 
Output Type 

byte int long float double 
Double 

date 
Date (written as serial day number 

time 
Time (written as fraction of day) 

date/time 
Date/time (integer gives serial day number, fractional part gives time) 

string 
Not written for matrices, written for datasets
