Article contents:== Outdated egg! This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for [[/eggref/5/matlab|the CHICKEN 5 version of this egg]], if it exists. If it does not exist, there may be equivalent functionality provided by another egg; have a look at the [[https://wiki.call-cc.org/chicken-projects/egg-index-5.html|egg index]]. Otherwise, please consider porting this egg to the current version of CHICKEN. [[tags: egg ffi]] [[toc:]] This page is maintained in the this package's [[https://github.com/abarbu/matlab-chicken|github repository]]. == matlab This Chicken egg provides matlab bindings. It makes matlab somewhat bearable. See ''matlab-example.scm'' for how a quick example. Note that this egg doesn't at the moment deal well with Matlab errors and it currently only supports marshalling lists, vectors and matrices of doubles. === Example (matlab "'hello'") (matlab "a=2+2") (matlab-get-variable "a") (scheme->matlab! "a" '(3)) (matlab-get-variable "a") (with-matlab-default-output-buffer (lambda (matlab-result-string) (matlab-eval-string "A=[[1,2,3];[4,5,6]]") (matlab-eval-string "B='Hi'") (matlab-eval-string "C=1") (matlab-show-variable "A") (matlab-show-variable "B") (matlab-show-variable "C") (matlab-eval-string "D=randn(2,2,2,2)") (display (matlab-result-string)) (matlab-show-variable "D") (matlab-eval-string "'Can also get the output from matlab'") (display (matlab-result-string)) (newline))) This does a few random things in matlab to show off the API. === High-level API <procedure>(matlab-eval-string s)</procedure> <procedure>(matlab-eval-strings . strings)</procedure> <procedure>(matlab . strings)</procedure> Execute one or more strings. ''(matlab . strings)'' returns the output of the command as a string. The return value of the other two calls is unspecified. These commands will start up an engine automatically if needed. <procedure>(matlab-append-to-path directory)</procedure> Performs an ''addpath''. <procedure>(matlab-load-variables filename)</procedure> <procedure>(matlab-save-variables filename . variables)</procedure> Performs a ''load'' or a ''save''. Saves the entire workspace if no variables are provided. <procedure>(start-matlab!)</procedure> Starts the Matlab engine. Note that calling this function multiple times has no effect. <procedure>(matlab->scheme variable-name)</procedure> Marshal a variable from Matlab to scheme. Only supports arrays and strings. <procedure>(scheme->matlab! variable-name object)</procedure> Assign to a Matlab variable. Only supports matrices, vectors, and lists. === Low-level API Many internal low-level functions for dealing with Matlab exist but they are of interest only to developers. Only those that may be of interest to users are listed here. <procedure>(matlab-start arguments)</procedure> <procedure>(matlab-stop engine)</procedure> Start or stop an engine. <procedure>(matlab-set-visible engine visible?)</procedure> <procedure>(matlab-get-visible engine visible?-pointer)</procedure> Get and set if the visibility of the Matlab UI. <parameter>*default-matlab-engine-command*</parameter> The parameters to use when starting the global Matlab engine. Currently ''-nosplash -nodesktop''. If you wish to add to these variables you can use the environment variable ''MATLAB_LOCAL_ARGS'' <constant>*matlab-engine*</constant> The current matlab engine. === License Copyright 2013 Andrei Barbu.
