indices= sub2ind(size(A_binary),(1:nb_tx_sensors_med),idx_selection);
here idx_selection=[6,9]
nb_tx_sensors_med=2
A_binary= 1x9

What's the index of the value in row 1, column 6 of a 4-by-5 matrix?
sub2ind([4 5], 1, 6)
Error using sub2ind (line 55)
Out of range subscript.
Trick question, since a 4-by-5 matrix doesn't have a 6th column.
Your case is slightly different, since you're asking for indices into the second row of a matrix with only one row.
To solve this you need to figure out why your code is asking for an element in a row and/or a column that doesn't exist and make it either stop or ask for an element in a row and/or column that does exist in the matrix.
