MATLAB: Matrix limits

matrix manipulation

Hello,

I currently have a set of about 200 2 by 200 matrices. I need to remove some values that are over a maximum value.

I need a way to set a limit for the first column (X co-ord), in order to remove the this value and the corresponding value in the second column (the Y co-ord).

Each matrix can have 1,2 or 3 values over the maximum, therefore I need to set a limit.

I appreciate this is probably a very simple issue for you guys.

Cheers

hei,

this might work:

 A(A(:,1)>limit,:) = []

hope this helps

What do you want to do with the 600? Delete it (making the vector shorter)? replace it with a different number? replace it with a char?

Suppose your matrix is called "M1", and your maximal value is MAXVAL,

M1(M1>MAXVAL)=[ ]; %to remove

M1(M1>MAXVAL)=-1; %to replace it with a value

A numeric example:

%random datas
A=randi([1 3],500,3);
B=randi([1 3],500,1);
%solution
X=linsolve(A,B)
