error from 'and' statement

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 )

thanks, the lower case worked spot-on :)
