Lets say a I have a 10 by 10 matrix with a random combination of numbers. So I want MATLAB to check a specific number is repeated a specific times. For example, what can I type if I want MATLAB to check if the number 1 is repeated 3 times in the 10 by 10 matrix?

sum(A(:) == 1) == 3

If you need to check for no.of times, assign a variable
c=find(A==1)
size(c)

You can apply size() to an expression
size(find(A==1))
size() is, either way, going to return a vector of dimensions. Which of those elements should George check? Will the answer vary in newer MATLAB versions which are changing the rules about whether various functions return row outputs or column outputs?
