Hi so I'm kinda new to using logic statements with MATLAB,
I am looping through a matrix of data, and seeing whether or not each value fits falls within a needed range, so I've tried using an AND statement within a for loop being:
if AND(data_reshape_3(count1, count2) > 0, data_reshape_3(count1, count2) <= 0.5);
However I am getting this error:
Undefined function 'AND' for input arguments of type 'logical'.
Any advise?
Thanks

You should use && or & to AND together two statements, depending on whether or not the individual statements evaluate to scalars or matrices.
e.g.
data_reshape_3(count1, count2) > 0 && data_reshape_3(count1, count2) <= 0.5
If you want to call the function though you have to use lowercase:
and( data_reshape_3(count1, count2) > 0, data_reshape_3(count1, count2) <= 0.5 )
