i want to perform operations on a table data, for that i need to access data of table using its index and again updated value of that index data should be stored at the same position.
- * For Example: * * A table having 3 columns and 10 rows, i have written following code but its not working,
for i=1:10
for j=1:3
if j==1
x=x<=5
else if j==2
x=x<=15
else
x=x<=25
end
end
end
Please correct my code......

for i=1:10
for j=1:3
if j==1
x(i,j) = x(i,j) <= 5
else if j==2
x(i,j) = x(i,j) <= 15
else
x(i,j) = x(i,j) <= 25
end
end
end

If Walter's interpretation is correct, then you do not need so many loops. A single loop approach will be:
A = [5 15 25];
for j = 1:3
x(:,j) = x(:,j) <= A(j);
end
or no loop way:
x = x <= repmat([5 15 25],10,1);
