MATLAB: How define input data type

input

when defining a function, for example

function y = func(x)

how can I define that x is of a specific type, like uint8?

Hi JD,

You could pass a counter variable i to your function as such:

i = 1;
while condition
  i = i+1;
end
function y = func(x, i)
  global A;
  y = x - A(i,2);
end

doc isa

A = rand(3,1) ;
A = uint8(A) ;
if isa(A,'uint8')
    fprintf('A is uint8\n')
else
    fprintf('A is not uint8\n')
end
