Hi, I need to convert a string into specific values increasing from 1 to 217 going in increments of 6.
I have a string that is consisting of numbers and letters and each number and letter needs to be changed into another number to create a vector. For example, 0=, 1=7, 2=13....a=61,b=67...z=217. I am not sure how to convert this string into a vector.

b=zeros(1,122);
b(double('0123456789abcdefghijklmnopqrstqvwxyz'))=1:6:211;%with 36 elements, I get z=211
newString=b(yourString);

c=zeros(1,211);
c(1:6:211)='0123456789abcdefghijklmnopqrstqvwxyz';
yourString=char(c(newString));
