How do I delete rows from a matrix based on the number of the row.

I have matrix A=[ 15 2 4; 19 3 7; 12 2 6; 10 4 9]

A second matrix which tells me the rows of A that need to be deleted.

BadA= [ 1; 3 ]

My matrices are much bigger but for right now this kind of simulation on smaller matrices will work.

Thank you

Assign the rows that need to be deleted to the empty array ‘[]’:

A = [ 15 2 4; 19 3 7; 12 2 6; 10 4 9]
BadA= [ 1; 3 ];
A(BadA,:) = []
