How to embed (insert) variable's that old strings or integers into line of code (%d?)

Hi guys,
I want to use variable's content (like v='name' or b=2.34) to be part of the code it's kind of like %d but as far as I understood it is not quiet like it. i'll explain:
Lets assume I want the code to automatically save figures or run for different inputs and want it to be done with replacing specific regions of the code with the different names of files ot inputs like this:
name='name_I_want' %name I want
b=231 %number I want
xnm=PA 'insert_name/integer_here' dirf(:,1);
ynm=PA 'insert_name/integer_here' dirf(:,2);
figure(1)
scatter(xnm,ynm, 1, 'filled');
title(' 'insert_name/integer_here' cell 2, XY scatter whole cell')
xlabel('nm')
ylabel('nm')
The lines i'm interested to insert\embed the new name\number are:
xnm=PA'insert_name/integer_here'dirf(:,1);
ynm=PA'insert_name/integer_here'dirf(:,2);
title(''insert_name/integer_here'cell 2, XY scatter whole cell')
I tried %d but I saw it only works with sprintf which is a variable of itself and not a way to 'intefere' with the code.
Thanks!
Amit.
