Help with populating a vector with 2 random variables

New to MATLAB and need to figure out how to populate a vetor with 2 random variables on both the negative and positive side of 0.

my variables are: 'numChannels' and 'channelSize' and would like to populate a vector of 'values = [ ]'

example1:

'numChannels = 3'

'channelSize = 1'

i would expect an output of 'values = [ -1, 0, 1]'

example2:

'numChannels = 5'

'channelSize = 0.5'

i would expect an output of 'values = [ -1, -0.5, 0, 0.5, 1]'

Any help would be greatly appreciated. Thanks

max_value = (numChannels-1)/2*channelSize;
values = linspace(-max_value, max_value, numChannels);
