I have a cell array that contains the following lines:

    '0,31:1.03 SPEED MEASURED 1 [rpm]'
    '0,31:1.04 MOTOR SPEED [rpm]'
    '0,31:1.08 MOTOR TORQUE [%]'
    '0,31:25.04 TORQUE REF B [%]'

I want to use them as titles for figures, but without the numbers preceding the text. For a figure that plots the measured speed, for example, I would want to have a title like this: SPEED MEASURED 1 [rpm]. How can I go about doing this?

Simpler with regexprep:

>> D = regexprep(C,'^\S+\s*','')
D =
    'SPEED MEASURED 1 [rpm]'
    'MOTOR SPEED [rpm]'
    'MOTOR TORQUE [%]'
    'TORQUE REF B [%]'

Thanks! I actually didn't know about this function, I've only heard of regexp before. Works well & looks neat!

a =  {'0,31:1.03 SPEED MEASURED 1 [rpm]'
    '0,31:1.04 MOTOR SPEED [rpm]'
    '0,31:1.08 MOTOR TORQUE [%]'
    '0,31:25.04 TORQUE REF B [%]'};
regexp(a,'(?<=\d\.\d{2}\s+).*','match','once')
