What is difference between min and min(min) ?

Hello,

[m,n]=size(x);
Min=min(min(x));

vs

Min = min(x);

[Arathi Sankar P]

minimum of a matrix is the matrix containing minimum of each column. Where minimum of minimum gives smallest element in the matrix.

[sam]

[m,n]= size(A);
Min = min(min(A));

this is not working for me

[John D'Errico]

@sam - Never just say something like "this is not working for me", and nothing more.

Since it DOES work, you need to say what it did do. If you got an error, then report the ENTIRE error message, so everything in red. If it did something strange, then say what it DID do, not just that it did not work.

Would you call up your doctor and ask (over the phone) for a diagnosis of your ailment, but not give a hint of what the ailment might be to the poor doctor? Would you ask your local auto mechanic to tell you what is wrong with your car, without seeeing the car, and without even telling the mechanic anything more than that your car won't start?

Just try it you will understand

A=[1 2 3;4 5 6]
m=min(A)  % give the minimimum of each column
n=min(min(A)) % is the minimum of the result m
%or instead of using min(min(A)) you can use 
B=A(:);
out=min(B)
