My randi matrix can have random values except one value, how do I generate it?

which value? are you talking about a particular index? and what would that value be?

I would suggest generating a mxn randi matrix, and just changing the one index to whatever value you wanted it to be.

Guessing that you mean that you want to randi() over a range of integer values but that there is a particular value that should never be generated, then:
valid_vals = setdiff(low_value:high_value, values_to_exclude);
result = valid_vals( randi(length(valid_vals), number_of_rows, number_of_columns) );

values_to_exclude = [3, 8, -5:-2]
just create a list.
