Need Help with matrix indexing

Hello!

I'm new to programming and the matlab.I have a matrix of 50000 rows and 10 columns.What i need to do is, getting rms values of every 200 rows of that matrix for each columns and then put the rms values in a new one.

I've tried this but that gives the "Index exceeds matrix dimensions."

Thanks @KALYAN ACHARJYA.

What if I try to do length(data)/200*10 matrix instead 1*10? Like every 200 rms for each row.

 c=mod(length(data),200);
  data=data(1:end-c,:);
      
      for i=1:200:length(data)
    dataR=rms(data(1:i,:));
      end

r=50000;
l=1;
mat_data=randi(100,[r,10]); % Here Data Matrix
result_rms=zeros(1,10);
for i=1:10
    result_rms(i)=rms(mat_data(l:l+199,i));
    l=l+199;
end
result_rms
