categorical conversion to integer

I have trained a neural network with two classes (0 and 1)
When i input an image of size 256x256 as:
y=classify(net,input)
the output y is categorica (either 0 or 1)l.
When I type cast it int 8
y=cast(y,'int'8)
I ger wrong values. I need values as it is classified by classifier in categorical form (0 as 0, 1 as 1).
Any suggestion?
Thanks

Perhaps something like this —
y = categorical([0 1])
y = cellfun(@str2double,categories(y))
y = int8(y)
.

create an ordinal categorical with valueset 0 and 1. Afterwards you can int8() the labels

uint8() gives back the class number. If you ordered them then you can work on them mathematically.
y = categorical(randi([0 1], 10, 1), [0 1], ["0", "1"])
uint8(y) - 1

M = categorical([0,1;1,0])
X = double(M);
Y = int8(str2double(categories(M)));
Z = Y(X)
