Some issues on building the compiled version of the MATLAB code¶

Reading config files (m files using eval)¶

When reading/writing files - such as config files - not everything will behave like in the matlab console.

The way teh config files were being read was not working - was simply using eval. It was necessary to read the file manually, adapting the suggestion found here: http://stackoverflow.com/questions/185461/reading-input-m-file-in-a-main-m-file#185660

(...)in a function we would create a text file, INP, containing our parameters.
We create this file in the directory returned by the ctfroot function.
Then, in MAIN, we would use the following to retrieve these parameters:

  eval(char(textread(fullfile(ctfroot, INP), '%s', 'whitespace', '');

See commit:d9262cdbfb38d9262cdbfb38 on the jabuilder-int branch.

Other input/output files¶

At the moment the input/output is done in the same folder where the the java class is being called from (hrir_final.mat and binsimecho.wav...).

Building the isvr jar¶

> /Applications/MATLAB_R2013b.app/bin/mcc -W "java:uk.ac.soton.isvr,HumanEcho" -d ./scratch -T "link:lib" -v "class{HumanEcho:./webapp/WEB-INF/mcode/gen_echo.m}" 

Contents of the isvr jar¶
