Please explain with an example what you have as an objective here...it isn't clear what you expect.

If it's just storing the numeric value of some parameter, you just use an array index to the position desired; if it is a combination of data types that are not all the same, then a cell array would be needed to hold the various types.

See the "Getting Started" section on matrix and array operations for examples of addressing modes/syntax.

Thankyou sir/mam for your reply .

The matrix is like this A(12,120). It has 120 spectrum slots. A=[1111100000000.....

0000001111111.....

00000010101......

:...........................]

U=[1:1000] it shows 1000 dynamic requests arriving for the spectrum. Actually my work is on elastic optical network. i want to assign /set the above spectrum slot (120 slots) capacity value to 12.5Ghz which Cslot=12.5ghz. but when i use array index then 12.5 appears at all places in A matrix. But i want that every elemnt capacity size is set to 12.5ghz so that it accepts the user request according to that. so i am not exactly getting how to set this 12.5 to each and every element?

i hope now i am cleary explianed..

thankyou

Unfortunately, no, it's not at all clear to me how any of the above three variables A, U, Cslot are related when just tossed out in isolation and what it is you're trying to do.

If the 12 in the A array size is trying to represent a bit pattern, then you would have to manipulate the individual elements of each array element; MATLAB doesn't implement a bit array. But, the string 1111100000000 isn't 12 but 13 "bits" if that is what it is intended to represent, either, so that also doesn't make any sense.

Show an example of what you have as input and what you would expect as output and the logic by which you get from one to the other. Doesn't have to have working MATLAB code, but we do need to be able to find out what is a working problem definition to be able to solve the problem.

1. First i initialize A matrix having 12 rows and 120 columns ( in this 12 are the links in the 4 node network topology and 120 shows the spectrum slots) and this 'A' matrix is in the form of 1's and 0's , as 1 represent spectrum is occupied and 0 represents spectrum slot is free. and i assume that the slot width (Cslot) as 12.5 Ghz.
2. Now, i have taken another variable as 'U' which takes the spectrum allocation requests say 1000 requests thats why i assigned u in the form of array from 1 :1000. and those 1000 requests are like 20 ghz, 12ghz,10 ghz,50 ghz etc.
3. Now i want to assign and allocate these above requests in the A matrix in place of 0's because 0 represents slot is free. But allocation in A matrix should be done intelligently as according to the slot width .for ex if suppose 50 ghz request come then 5 slots are required to fulfill it so like that i have to do..
4. i want to know whether i have to do it element by elemnt for this or is there any other method to allocate it in one step as slots are 120 and requets are 1000.
