hi... Is there any code in MATLAB which we can find the array of a number in a matrix? for example I have a matrix like [1 2 3;4 5 6;7 8 9], and I know there is number 5 in my matrix but I don't know in which array is it, now I want to find it with a simple function code... thanks for your help
Use the find() function to get the row and column index of all matching elements.
>> a = [1,2,3;4,5,6;7,8,9]
a =
1 2 3
4 5 6
7 8 9
>> [row,col] = find(a==5)
row =
2
col =
2
Here we see that the element in row 2, column 2 is indeed equal to 5.

row =
2
col =

Here we see that the element in row 2, column 2 is indeed equal to 5.
Just use the find() function with equality comparison operator.
[row,col]=find(array_name==value)
It will return the row number in row variable and column number in column variable.
