channel coefficients from mimochan() in embedded matlab

[preethi_k4]

Hi All,

For implementing MIMO in Simulink i am using mimochan() in matlab function. The channel object is created and i used filter() to pass the modulated signal. It worked fine. Now, for the PathGains of the channel object, i used the follwing code

coder.extrinsic('mimochan')
chnl = mimochan(2,2,0.0001,40)
out_1 = filter(chan,data)
chnl_coeff = chan.PathGains

It is giving me an error. I also tried by intializing the chnl_coeff with zeros and then trying to access PathGains, in vain.

Even the line chnl.StorePathGains = 1 when included seperately is also giving the same error.
coder.extrinsic('mimochan')
chnl = mimochan(2,2,0.0001,40)
chnl.StorePathGains = 1
out_1 = filter(chan,data)

Did i missed out anyting while using mimochan() in simulink matlab function? I am out of ideas...
The same code is working in normal .m files..

Request to help me out from this problem..Thanking you in advance
