I have a 720x20 matrix how can i subtract 1x20 matrix from it?

    clc
clear
signal_factor=10;
format long
folder='E:\Pressure split';
filetype='*.xlsx';  
f=fullfile(folder,filetype);
d=dir(f);
for k=1:numel(d);
  data{k}=xlsread(fullfile(folder,d(k).name));
end
data=cell2mat(data);
A=data(:,1);
A=A(80:end,1);
n = 720;
m = numel(A);
out = reshape([A(:);nan(mod(-m,n),1)],n,[]);
out=out*signal_factor;
min=min(out);

This is my code, it generates 720x20 matrix and the min also generates 1x20 matix what i want is to subtract first value of min from out (subtract a constant value from all the 720 values) and so on.

[KSSV]

you want to subtract each min from 720*20 matrix? Or subtract each column with respective min?

[Andrzej Miekina]

use repmat

[PRUDHVI RAJU]

min=repmat(min,720,1); % 720 rows same 'min' row matrix

sub=out-min;

Don't use the built-in function min as a variable

Answer 1

[Adam]

res = bsxfun( @minus, out, minVal);

should work if I understand correctly what you are asking.

Don't ever call a variable 'min' though, especially not when you are also using the function 'min' which you hide after your variable gets created (but really just never do it, irrespective of whether you are using the 'min' function in your code or not).

Thanks it works, and thx for the tips, i changed it to minVal.
