MATLAB: How to programmatically add a block from Audio Toolbox to Simulink

Question

I have added a Simulink "In File" block programmatically:

add_block('simulink/Sinks/To File',...)

How do I add a block from Audio Toolbox?

I tried

add_block('Audio Toolbox/Sources/From Multimedia File',..)

but it fails with "There is no block named 'Audio Toolbox/Sources/From Multimedia File'".

Hi,

In order to add a block you shouldn't look at the library name because its file could be named differently. This is that case.

You should point:

'dspvision/From Multimedia File'

If you want to add any block, you can check its real source by selecting it and in the command window executing

get_param(gcbh,'ReferenceBlock')

Except if the block comes from built-in, in that case you should look at the

'BlockType'

property.

Hope it helps.
