I don't understand what is the problem.....i tried it, but get an error. So plz help me to solve the problem...

"Write a function called integerize that takes as its input a matrix A of non-negative integers of type double, and returns the name of the “smallest” unsigned integer class to which A can be accurately converted. If no such class exists, the string 'NONE' is returned. For example, if the largest integer A is 14, then the function would return 'uint8', but if the largest integer in A is 1e20, then the function would return 'NONE'."

Hint: see functions intmax() and max()

mavValue = max(A(:))
if maxValue < intmax('uint8')

and so on...

[Muhammad Usman Saleem]

@image i am using that code now , but getting the below mentioned error...

function integ=integerize(A)
mavValue = max(A(:))
if maxValue < intmax('uint8')
    integ='uint8';
if maxValue<intmax('uint16')
    integ='uint16';
    if maxValue<intmax('uint32')
        integ='uint32';
        if maxValue<intmax('uint64')
            integ='uint64';
        else
            integ='NONE';
        end
    end
end
end

Error i got is

      Your solution is _not_ correct.

guide me where i need corrections.. Thanks in advance

@image in another approach i use..

function integ=integerize(A)
if  int(A) && uint(A)
    if max(A)<=intmax('uint16')
    integ='uint16';
elseif max(A) <= intmax('uint32')
    integ='uint32';
elseif max(A) <= intmax('uint64') 
    integ='uint64';
elseif mod(A,1)=>0
    integ='NONE';
    end
end
end

but the error remains same as mentioned above..

Muhammad, It looks like you've gotten your own thread started in this other thread so we'll just have the discussion over there.

[Mostafa Farhoudi]

function integ=integerize(A)
integ = 'none'; 
maxValue=max(A(:));
disp(maxValue);
if maxValue <= intmax('uint8')
integ='uint8';
elseif maxValue<=intmax('uint16')
integ='uint16';
elseif maxValue <= intmax('uint32')
integ='uint32'; 
elseif maxValue <= intmax('uint64')
integ='uint64';
else
integ='NONE';
end
end

[Pranash Azrot]

yaar mera answer teek see.

 function u = integerize(A)
g =max(max(A));
if (g>255 && g<=intmax('uint16'))
    u = 'uint16';
elseif (g<0 || g>intmax('uint64'))
    u = 'NONE';
elseif (g>intmax('uint16') && g<=intmax('uint32'))
    u = 'uint32';
elseif (g>intmax('uint32') && g<=intmax('uint64'))
    u = 'uint64';
else 
    u = 'uint8';
end
