How to do a same function on variables with similiar parts in their names?

let's say we have variables named as: Time_p1 and Voltage_p1

Time_p2 and Voltage_p2

Time_p3 and Voltage_p3

and so on.

we want to do the following set of comments on each of them.

for Time_p1 and Voltage_p1:

pulse1=[];
pulse1(:,1)= Time_p1;
pulse1(:,2)= Voltage_p1

for Time_p2 and Voltage_p2:

pulse2=[];
pulse2(:,1)= Time_p2;
pulse2(:,2)= Voltage_p2;

and so on.

how can we do this in a simple way?

That's discouraged, but go on ...

Instead of having multiple variables names that only differ by a number, store them in a numeric array (if they can be combined into a rectangular region) or a cell array (if they can't.)

x = (1:5).';
y = x.^(0:6)

y = 5×7

1 1 1 1 1 1 1 1 2 4 8 16 32 64 1 3 9 27 81 243 729 1 4 16 64 256 1024 4096 1 5 25 125 625 3125 15625

Instead of defining y0 = x.^0, y1 = x.^1, y2 = x.^2, etc. use y(0+1) for x.^0, y(1+1) for x.^1, y(2+1) for x.^2, etc.
