finding lower case letters

If I set x='sTring'

is there any possible way that I can detect the position of the upper case letter and add a number 'n' to it so that it'll change to letter to something else? thank you.

x = 'aStringWithCamelCaseThatHasSomeCapitalLetters';
y = x;
z = x;

y(ismember(x, 'A':'Z')) = '?'

or

z(ismember(x, 'A':'Z')) = x(ismember(x, 'A':'Z'))+1
