Hi,
How can i concatinate 20 , 4D signals
I1 = rand(32,32,1,13) ;
I2 = rand(40,32,1,13) ;
...
I20 = rand(47,32,1,13) ;
Catq1=cat(4,I1,I2);
The above give me error? What can i do?

You want to concatenate on the dim which is not same for both, right?
Catq1 = cat(1,I1,I2);
% OR
Catq1 = [I1;I2];

And how to provide the CNN: predict DL block to the ready machine.
1. I have data built in 4D format, my CNN machine only use this format for learning and prediction in matlab.
2. I have built a model in SIMULINK but there is a problem with entering data to the Predict block, error message:
Available formats are double non-complex matrix, a structure with or without time, or a structure with MATLAB timeseries as leaf nodes. All formats require the data to be finite (not Inf or NaN).
How to solve it?
