Removing element of array at random

I have a 200 x 1 matrix of random numbers and I want to remove 10 numbers from the array at random.

Here is sample data i used:

a = 0; %mean

b = 1; %standard deviation

random_num = b*randn(200,1)+a; %generates random numbers

How can I remove, at random 10 numbers from the random_num variable?

a = 0;
b = 1;
rn = b*randn(200,1)+1;
ix = randperm(200,10) % indices of elements to remove

ix = 1×10

145 76 40 81 116 61 82 94 113 182

rn(ix) = []; % remove elements
