for j=1:3
symbolList = ['o', 'x', 's', 'd','.', '^', 'v', '>', '<', '*','p','h','+'];
symbol = sprintf('r%s-', symbolList(mod(j-1,length(symbolList))+1));
plot(a(1,:),b(1,:).*25.4, symbol, 'LineWidth', 0.1);
hold on
plot(c(1,:),d(1,:).*25.4, symbol, 'LineWidth', 0.1);
hold on
plot(e(1,:),f(1,:).*25.4, symbol, 'LineWidth', 0.1);
hold on
end %for 3 plots

Thank you, I wanted to numerically add in ascendinr order the next subsequent symbol for the 1st, 2nd and 3rd plots but I was confused. The accepted answer herein explains it better.

Ran in:
I'm not sure why you're using a loop to create the same plots three times with different symbols. Are there other columns (of a,b,c etc) that need to be plotted as the loop increments?
Alternatively, do you mean to simply plot each of these three things once, but automatically using a unique symbol for each?
If that's the case, and your data doesn't lend itself to indexing, then you might consider turning symbol into a function. That way you can just do something like this:
symbolList = ['o', 'x', 's', 'd','.', '^', 'v', '>', '<', '*','p','h','+'];
symbol = @(k) sprintf('r%s-', symbolList(mod(k-1,length(symbolList))+1));
hold on
plot((1:10)+5, symbol(1), 'LineWidth', 0.1);
plot((1:10)+10, symbol(2), 'LineWidth', 0.1);
plot((1:10)+15, symbol(3), 'LineWidth', 0.1);
Obviously I'm just using placeholder data here.

Thank you very much. I was confused and you clearly explained in words what I wanted to do. I guess I can do something similar for line type too. I need more practice to fully understand these functions. Great answer!!
