Write a function called integerize that takes as its input a matrix A of integers of type double, and returns the name of the “smallest” signed integer class to which A can be converted without loss of information. If no such class exists, the text 'NONE' is returned. For example, if the smallest element of A is -100 and the largest is +100, then the function would return 'int8'. As another example, if there is an element of A equal to -1e20, then the function would return 'NONE'
My code is;
function x = integerize(A)
maxA = max(A(:));
minA = min(A(:));
if maxA<=((2^7)-1) && minA>=-(2^7);
x='int8';
elseif maxA<=((2^15)-1) && maxA>((2^7)-1) && minA>=-(2^15) && minA< -(2^7);
x='int16';
elseif maxA<=((2^31)-1) && maxA>((2^15)-1) && minA >=-(2^31) && minA <-(2^15);
x='int32';
elseif maxA<=((2^63)-1) && maxA>((2^31)-1) && minA >=-(2^63) && minA< -(2^31);
x='int64';
else
x=NONE;
end
end
But it is noncorrect;
Problem 1 (integerize):
Testing with argument(s) 0

Testing with argument(s) -1

Testing with argument(s) -127

Your solution is _not_ correct.
I dont understant my fault pleas help me

You are only returning the signed integer classes. You have forgotten the unsigned integer classes like uint8

That's correct, there is no function named NONE in MATLAB or any MathWorks products and no variable by that name in your code. But reread the homework assignment carefully -- in the case where none of the integer types fit, what exactly should be returned? What type should that return value be?
