Hi all,
I need to make some variables appear as symbols so I can get the answer in terms of them. When i make them symbolic however, it makes the whole matrix they're in symbolic, even though they only appear in two columns.
How can I make the other values in the matrix normal?
Example to explain:
syms E A
K=[1 1 2 E A
2 1 3 E A
3 2 3 E A];
When I then try to use the number values, in cases such as:
B=A(K(2,1),2) (Assuming that A is a square m by n matrix.)
This gives an error as K(2,1) is the symbol '2' and not the integer '2'.
How can i make it read like an integer? Or make it not be a symbol?
I hope this makes sense, thanks in advance
