Selection of logical data

Hello,

I have a matrix with this form:

1 156 NaN NaN NaN

1 157 NaN NaN NaN

1 158 1.85185185185185 2.63157894736842 2.04081632653061

0 159 NaN NaN NaN

1 160 1.96078431372549 3.44827586206897 1.56250000000000

I wanna form a new matrix with this one where I would only have the rows that are true (=1) and keep all the column.

Best regards,
