how to read the certain row and column from the cell array?

HI,

I am working with the large data in which i need to extract the meaning data what is a way to go forward.

FOr Example:

x = [2 3 3 4 45 5 6 5 6 7 5 87876 876 889 8 98 9 079 0 ]

y = [2 3 344 5 546 676 65 7 6 67 98 9 8 90 79 23 4 34]

if i need to pick certain range of number from x and y how would i do that?

Example:

 x = [2 3 3 4 45]
 x(1:3)
 
 ans =
     2     3     3
 
 y = [8 90 79  23 4 34]
 y(4:6) 
 
 ans =
    23     4    34

what if, x = 1 2 3 4 4 5 5 6 7 7 88

1 2 3 3 4 4 55 6 67

one variable but have 2 arrays and I want to access the certain data?

That depends on the dimension of the matrix.

For example:

x =  [2 3 4 4 5 5 6 7 7 88 ; 1 2 3 3 4 4 55 6 67 4] %10 columns and 2 rows

x(1,:)  %first row, all columns
ans =
     2     3     4     4     5     5     6     7     7    88
x(2,:) %second row, all columns
ans =
     1     2     3     3     4     4    55     6    67     4
x(1,5:10) %first row and last six elements of the column
ans =
     5     5     6     7     7    88
     
x(rows,columns)
