How can I get MATLAB to return Alpha1=4

Write a single MATLAB statement that will accomplish the stated purpose. Assume a text string TS1 has already been defined. Place the numeric index of the first alphabetic character in TS1 into Alpha1. Example: TS1='%@3Gb6' returns Alpha1=4.

This will work:

TS1='%@3Gb6';
Alpha1 = regexp(TS1, '[A-Za-z]')

Alpha1 =
