How can I change SPI mode of an Arduino through Matlab?

I use the MATLAB® Support Package for Arduino® Hardware to control devices with SPI communication. Matlab r2014b version with an Arduino uno.

It seems that modifying the mode has no effect. Setting mode to 0 should idle clock low and setting it to 3 for example should idle clock high. But it doesn't...

Code example:

a = arduino('com9'); dev = spidev(a, 4, 'mode', 0);

It is a bug in MATLAB R2014b. If you are still looking for a fix, please contact MathWorks technical support to get a patch.
