Hello all

I have a bit of a problem. My simulink model has an dimension error, but i cant understand why.

I need to perform the calculation x * x^T, in order to get a 5x5 result. (x is 5x1). But simulink "wants" to do x^T * x, to get a 1x1 result.

When i use the same block (copy-pasted), only connected to a display, it works as intended.

I have attached the files nessensary to run the model. The error takes place in a block called "ID block"

I have found, that if i disconnect a signal called "theta" from another block called "controller", the error disappears.

You need to attach a reshape block. See the image
