The Euler phi function ϕ (n) computes the number of integers between 1 and n that are relatively prime (also known as coprime) to n.Two integers are relatively prime if there is no integer greater than one that divides them both. In other words, their greatest common divisor is one.

Euler's method is a numerical method to solve first order first degree differential equation with a given initial value.

Apr 08, 2020 · by Tutorial45 April 8, 2020. written by Tutorial45. The Euler method is a numerical method that allows solving differential equations ( ordinary differential equations ). It is an easy method to use when you have a hard time solving a differential equation and are interested in approximating the behavior of the equation in a certain range. Here we will see how you can use the Euler method to solve differential equations in Matlab, and look more at the most important shortcomings of the method.

Polynomial variable, specified as a symbolic variable, expression, function, vector, or matrix. If x is a vector or matrix, euler returns Euler numbers or polynomials for each element of x.When you use the euler function to find Euler polynomials, at least one argument must be a scalar or both arguments must be vectors or matrices of the same size.

Euler's theorem states that a ϕ ( n) ≡ 1 ( m o d n) if and only if the two positive integers a and n are relatively prime. Show that the Euler phi function ϕ ( n) satisfies Euler's theorem for the integers a = 1 5 and n = 4. a = 15; n = 4; isCongruent = powermod (a,eulerPhi (n),n) == mod (1,n) isCongruent = logical 1.
