# An easy way to apply a transformation to many data points

Hello, I have a list of over 100 data points in the form:
BAM_186_Torque_8Nov_0656 BAM_186_Torque_8Nov_0657 BAM_186_Torque_8Nov_0658
etc...
I am current applying an RMS function to them using the following code:
RMS_BAM_186_Torque_8Nov_0656 = rms(BAM_186_Torque_8Nov_0656); RMS_BAM_186_Torque_8Nov_0657 = rms(BAM_186_Torque_8Nov_0657); RMS_BAM_186_Torque_8Nov_0658 = rms(BAM_186_Torque_8Nov_0658); RMS_BAM_186_Torque_8Nov_0659 = rms(BAM_186_Torque_8Nov_0659); RMS_BAM_186_Torque_8Nov_0700 = rms(BAM_186_Torque_8Nov_0700); RMS_BAM_186_Torque_8Nov_0701 = rms(BAM_186_Torque_8Nov_0701); RMS_BAM_186_Torque_8Nov_0702 = rms(BAM_186_Torque_8Nov_0702); RMS_BAM_186_Torque_8Nov_0703 = rms(BAM_186_Torque_8Nov_0703);
My question is, how could I put these into an iterative loop to clean up my code and make my programming easier?
Thank you!

Put your data points into the columns A(:,i) of a matrix instead. Then just do
rms_A=zeros(1,size(A,2));
for i=1:100
rms_A(i)=rms(A(:,i));
end
