Hello, I have a structure which is as follow:

SatGlobal.aChanData(all).PRN

The above structure contains 12 satellite PRN codes inside the PRN property. Now I want to extract this number of satellites and store them into a variable to find the size of the matrix to create a control state for a loop later.

Actually the size of this property varie depending upon the number of available satellites.

I did it somehow in the past but lost that code and I can't remember how I did it actually.

I am currently using the following code but it is giving me only one SV.

Please note that the PRN value is different for each satellite and I want to extract the all available channels.

SV = SatGlobal.aChanData(1,1:end).PRN;
num_sv = length(SV)
for i = 1:num_sv
%     run a loop for all calculations
end 
% This code only store 1 value in the SV now and first it was storing all
% the available channels
