IF-statement for matrix/vector

Hi,

I have a 146652x1 matrix (vector) and I want to check each column for a defined condition. For example if the value is greater than 1.

Example:

IF "column_value" > 1

column_value / 0.001

So with this method, I wanto to checkout every single column in my matrix.

How do I code this?

As you mentioned that the matrix having size 146652x1, which means it has 1 column. Prefer logical conditional statement.

idx=mat_data>1;

It's return logical data 1, where the value greater than 1, else 0.

Or

If you mat data having multiple columns and rows, force all elements greater than 2 to be Zero

results=mat_data>1 & mat_data 

Or

If you wish to check individual cloumn data

for i=1:coumn_num
if mat_data(:,i)>1
    % Do
end
end
