Could anyone help me with this problem?
I need to multiply an expression by 'x' and get the result.
The expression is: A1 - A1 * x + 2 * A2 * x - A2 x ^ 2 + 3 * A3 * x ^ 2 - A3 * x ^ 3 + 4 * A4 * 4 + 5 * A5 * x ^ 4 - A5 * x ^ 5 - 1
I need to multiply it by 'x'. How to do?
Initially you have an error in your expression A2 x^2 , considering it as A2*x^2 , let's go to the problem.
Matlab has a very simple syntax:
If you have a and want to multiply a times x , just use
a*x
If a is something more complex than just a simple variable or number, you may want to use parentheses to do the multiplication correctly, thus:
(a)*x
