How can I write these formula in matlab ?

Hi, In this scenario, I have values from 1 to 100

RegdIg=[RegdIg1;RegdIg2;RegdIg3;RegdIg4;RegdIg5;RegdIg6;RegdIg7;RegdIg8; ................. ,RegdIg100] gs=gs1+gs2+gs3+gs4+gs5+gs6+.................+gs100

How can I write these formulas in matlab ?

The question is not clear. Do you have a bunch of variables called "gs1", "gs2", ...? If so, this is a really bad idea. Use one variable instead as a vector. Then summing up works by the sum() command.

Dear Mr.Jan,

Let me explain this for you.... Actually, we have (100) clusters ..... we have gs1 & RegdIg1 for cluster number(1) In the same way, we have gs2 & RegdIg2 for cluster number(2)....... .....gsn & RegdIgn for cluster number(n), where gs is equal to the sum of the gs in all clusters that's mean gs=gs1+gs2+ ......+gsn RegdIg is a matrix , where RegdIg=[RegdIg1;RegdIg2;.......;RegdIgn].

You just have to do it like you did

gs=gs1+gs2+ ......+gs100;
RegdIg=[RegdIg1;RegdIg2;.......;RegdIg100]

Yeah, not fun to have to write it down a hundred times, but you made your bed so you now have to lie in it. Or you can not create those variables in the first place, and use an indexed array like everyone is telling you to. Then it's a simple for loop or a call to sum().

 both gs & RegdIg are having different formulas . How can I calculate all the values of  (gs) as sum of all gs in the clusters ....gs=gs1+gs2+ ......+gs100;
and in the same way. how can I put.each value of RegdIg as a matrix RegdIg=[RegdIg1;RegdIg2;.......;RegdIg100];
