phased.FreeSpace Error invoking stepImpl
显示 更早的评论
I am running a radar model in Simulink and when I change PRI this will 'sometimes' pops up and terminates my simulation. I don't know what it means or how to fix.
-----
An Error occurred while running the simulation and the simulation was terminated
caused by:
MATLAB Systemblock 'tgt_Rx channel' error occurred when invoking 'stepImpl' method of 'phased.FreeSpace'
The error was thrown from
'c:...\+phased\FreeSpace.m' at line 173.'
'c:...\+phased\+internal\abstractFreeSpace.m' at line 481.'
Changing the complexity (from real to complex) on input 1 is not allowed without first calling the *release()* method.

Looks like your signal changed the complexity during your simulation. An easy way to fix this is to always convert your input to complex before feeding it to the FreeSpace block.

I don't know what's in your model so I cannot comment much on this.
