About M2SCI tools
Generally speaking about tools to convert Matlab files to Scilab
Description
Scilab includes useful tools to convert Matlab M-files to Scilab.
Taking a Matlab M-file, mfile2sci
modifies this files so that it can be
compiled by Scilab. After that this compiled code is converted to a "tree" of instructions
by macr2tree
. This "tree" is an imbrication of Scilab lists and tlists and
is the basis for conversion. Each instruction of this "tree" is converted to Scilab and
inference is done to known what are the variables. Once this "tree" is converted to Scilab,
code is generated using tree2code
.
All tlists used for coding this tree (and we call "MSCI tlists") are listed below:
- funcall
tlist representing a function call created by
Funcall
- operation
tlist representing an operation created by
Operation
- variable
tlist representing a variable created by
Variable
- cste
tlist representing a constant created by
Cste
- equal
tlist representing an instruction created by
Equal
- ifthenelse
tlist representing an IF/THEN/ELSE control instruction created inside M2SCI kernel functions
- while
tlist representing a WHILE control instruction created inside M2SCI kernel functions
- selectcase
tlist representing a SELECT/CASE control instruction created inside M2SCI kernel functions
- for
tlist representing a FOR control instruction created inside M2SCI kernel functions
The contents of these tlists is described in corresponding help pages.
Operations are converted using a function named %<opcode>2sci
with opcode
the Scilab code for this operator. See help page for overloading to have these codes. All
these functions are already written and are in directory SCI/modules/m2sci/macros/percent/.
Function calls are converted using a function called sci_<Matlab_function_name>
.
Some of these functions have been written and are in directory SCI/modules/m2sci/macros/sci_files/.
We are working on increasing the set of Matlab functions converted. However, everybody can
written such functions using help page sci_files.
Inference is done using tlists of type "infer" containing fields:
- dims
list of dimensions
- type
"type" tlist
- contents
"contents" tlist if a Cell or a Struct
Type is a tlist of type "type" containing fields:
- vtype
data type
- property
property
To have more details about inference see help page for m2scideclare.
