MATLAB: Is it possible to to use the method mwArray::SetData in MATLAB Compiler 4.10 (R2009a) with a constant as the first argument

MATLAB Compilermxarray

I want to pass a variable to mwArray::SetData declared as cont. However, it is not possible mwArray::SetData has no signature with first argument as const.

The ability to pass constant variables to mwArray::SetData is not available in MATLAB Compliler 4.10 (R2009a).

To work around this issue typecast the variable before passing it to mwArray::SetData to ensure that it is not a constant.

MATLAB: Am I getting a java error when trying to run the java class compiled by MATLAB Builder JA 2.2.3 (R2011b)

The MathWorks javabuilder.jar java library is missing. Make sure the javabuilder.jar file is added to the java class path when running your java class, as below:

java -classpath <mwroot>/toolbox/javabuilder/jar/javabuilder.jar:foo.jar foopackage.fooclass

where mwroot is either the MATLAB root directory (if running against MATLAB) or the MCR root directory (if running against the MCR).

If you have another java application that utilizes the compiled java class, make sure to also import it as below:

import com.mathworks.toolbox.javabuilder.*

MATLAB: Can I use ADDPATH in a compiled application from MATLAB Compiler 4.10 (R2009a)

This change has been incorporated into the documentation in Release 2011a (R2011a). For previous releases, read below for any additional information:

It is not recommended to use ADDPATH in a deployed application. As a workaround, use paths relative to MATLABROOT or CTFROOT.

For example, change code like this:

addpath(my/data/directory)
fp = fopen('data.file', 'r');

To code like this:

fp = fopen(fullfile(ctfroot, 'my', 'data', 'directory', 'data.file'));
