how to empty the cell of any array whose index is in another matrix

I want to know how to empty the cell of any array, when the index of that particular cell is given in another matrix.

eg: I have an array as

A={[1 2], [10 11], [15 12], [16 17], [18 2]}

a matrix having index as

B=[2 3 5]

Now i want to empty the cells with index given in matrix B and want an output as:

A={[1 2],[ ], [ ], [16 17], [ ]}

I am a begineer in MATLAB, so pardon me if my question is not clear.

Answer 1

[Walter Roberson]

A={[1 2], [10 11], [15 12], [16 17], [18 2]}

A = 1×5 cell array
    {[1 2]}    {[10 11]}    {[15 12]}    {[16 17]}    {[18 2]}

B=[2 3 5]

B = 1×3

2 3 5

A(B) = {[]}

A = 1×5 cell array
    {[1 2]}    {0×0 double}    {0×0 double}    {[16 17]}    {0×0 double}
