Hi everyone,
Please show me how to find multiple numbers in a matrix. Lets say I have a matrix:
A = [1 2 3 3 5 6; 7 8 3 3 5 12; 13 14 3 3 17 5];
So I want to find number 3 in the matrix. I used this code:
for i=1:3;
for j=1:length(A);
if A (i,j) == 3;
b (i,j) = 1;
else
b (i,j) = 0;
end
end
end
Then I got:
b = [0 0 1 1 0 0; 0 0 1 1 0 0; 0 0 1 1 0 0]
But my problem is how if I want to find position of 2 numbers in a matrix, for example 3 and 5. I want the answer look like this:
b = [0 0 1 1 1 0; 0 0 1 1 1 0; 0 0 1 1 0 1]

A = [1 2 3 3 5 6; 7 8 3 3 5 12; 13 14 3 3 17 5];
b=A==3 | A==5
