Does this formula wrote in correct way in the matlab

hello i have this formula y= -0.0459 E/(√(E²-m²))/(1-e^(0.0459 E/(√(E²-m²)))).√(E²-m²)

In matlab y= ((-0.0459*x./sqrt(x.^2-m^2))./(1-exp(0.0459*x./sqrt(x.^2-m^2)))).*sqrt(x.^2-m^2)

does this correct please

Answer 1

[Roger Stafford]

At the right end of your formula, ".√(E²-m²)", are you sure the dot signifies multiplication? If it were to mean that, as I have pointed out in your previous thread, this would cancel out the earlier division by the same value, "√(E²-m²)". That suggests that the dot may signify an operation other than multiplication, though I am at a loss as to what it might be. You had better take a more careful look at wherever you obtained this formula from.

yes the dot signifies multiplication

Looks like it. Does it give the correct answers for given inputs? If so then it is ,assuming you test edge cases.

[shayma mohammed]

it gives an imaginary number

[Roger Stafford]

Again, the reason for that is that you are using values of x that lie between -m and +m which produces the square root of a negative number, and that gives rise to imaginary and complex numbers. There is no mystery here.
