convert double array to categorical

Hi there!

I want to convert double array to categorical.

Double array is b:

>>a = unique(b)

>> a =

0

0.0100

0.0200

0.0300

0.0400

0.0500

0.0500 ( I don't know why there are two 0.0500)

.......

0.3400

0.4600

0.6600

1.4300

>> whos b

>> Name Size Bytes Class Attributes

b 793505x1 6348040 double

>> categorical(b)

>> Error using categorical (line 434)

Unable to create default category names. Specify

category names using the CATEGORYNAMES input argument.

I got this error while converting data type and I could not figure out where the question is. Hope you guys can help me.

Thank you very much in advance.

Consider using discretize.

x = rand(10, 1);
c = discretize(x, 0:0.25:1, 'categorical');
t = table(x, c)
