I have the following string
hue = '10 20 30 40 50';
That I want to turn into a vector of those 5 values
hue_vec = [10 20 30 40 50];
How can I do this? Thanks in advance!

hue_vec = str2double(regexp(hue,'\d+','match'))

If you have decimals then the expressions would be:
hue_vec = str2double(regexp(hue,'\d*[\.]?\d*','match'))

Very simple, very efficient, no evil eval:
>> hue = '10 20 30 40 50';
>> vec = sscanf(hue,'%f',[1,Inf])
vec =
10 20 30 40 50
