How can I count the number of elements of a given value in a matrix?
Does anyone know how to count the number of times a value appears in a matrix?
For example, if I have a 1500 x 1 matrix M (vector) which stores the values of weekdays (1 - 7), how could I count how many Sundays (1), Mondays(2), ... , Saturdays(7) are stored in M?
