Hi, I need to resample a 3d data matrix via function

The matrix are from a starting point 4096x20x11 meaning samples x signal x points. What I need is to resample the first dimension turning that 4096 into 2048, 1024 etc without touching the other two dimensions

I tried with resampling using the function resample this way:

function [resampled_signals] = resample(data,orig_fs,target_fs)
    
    [p,q] = rat(target_sr/orig_sr);
    resampled_signals = resample(data,p,q,'Dimension',1);
    
end

I keep receiving the prompt

"Error using resample

Too many input arguments"

And I don't know what else to do. Thx in advance.

nope but now that i realize that, which is pretty silly on my part i will change the original function and see if it works. Thx for pointing that out.
