## How do you find the complex number in Scilab?

Predefined Scilab functions for complex numbers complex() : creates a complex number. conj() : creates the complex conjugate of a complex number. imag() : extracts the imaginary part of complex numbers, polynomials, or rationals. imult() : multiplication by i the imaginary unitary.

### What is complex magnitude?

The complex magnitude (or modulus) is the length of a vector from the origin to a complex value plotted in the complex plane. For a complex value, | a + b i | is defined as a 2 + b 2 .

#### What is complex number in Scilab?

In Scilab we define the complex numbers by using the special constant %i , in the following manner: –>c = 2 + 3*%i c = 2. + 3.i –> This way we’ve defined a complex number c which has the real part 2 and the imaginary part 3i . A purelly imaginary complex number is defined like this: –>c = 5*%i c = 5.i –>

**How do you find the magnitude of a number?**

For numbers such as 1, 2, 3, and so on, the magnitude is simply the number itself. If the number is negative, the magnitude becomes the absolute value of the number. For example, the magnitude of 10 is 10. The magnitude of -10 becomes the absolute value of -10, which is 10.

**What is Funcprot in Scilab?**

Scilab functions are variable, funcprot allows the user to specify what scilab do when such variables are redefined. *If prot==0 nothing special is done *If prot==1 scilab issues a warning message when a function is redefined (default mode) *If prot==2 scilab issues an error when a function is redefined.

## What is complex number formula?

Complex Number Formula A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit, that satisfies the equation i2 = −1. In this expression, a is the real part and b is the imaginary part of the complex number.

### What is the magnitude and phase of the complex number?

The angle or phase or argument of the complex number a + bj is the angle, measured in radians, from the point 1 + 0j to a + bj, with counterclockwise denoting positive angle. The angle of a complex number c = a + bj is denoted c: c = arctanb/a.

#### How do you write exponential in Scilab?

Exponentiation is right-associative in Scilab contrarily to Matlab® and Octave. For example 2^3^4 is equal to 2^(3^4) in Scilab but is equal to (2^3)^4 in Matlab® and Octave.

**How do you write polar form in Scilab?**

[Ro, Theta]=polar(A) returns the polar form of A i.e. A=Ro*expm(%i*Theta) when Ro symmetric >=0 and Theta hermitian >=0.

**How do I find the magnitude of a matrix?**

You can measure the “magnitudes” of matrices by using matrix norms. If you stack up the columns of an n×n matrix A successively with the first column on top, you get a long vector v in Rn2. The Euclidean norm of this vector (i.e. ‖v‖2) is called the Frobenius norm of the matrix and it is denoted by ‖A‖F.

## What does CLF mean in Scilab?

clf – Clears and resets a figure or a frame uicontrol. Graphics.

### What is feval command in Scilab?

Description. Multiple evaluation of a function for one or two arguments of vector type : z=feval(x,f) returns the vector z defined by z(i)=f(x(i)) z=feval(x,y,f)

#### What is the modulus of an imaginary number?

The modulus of a complex number is the square root of the sum of the squares of the real part and the imaginary part of the complex number. It can be calculated using the formula |z| = √(x2 + y2).

**How do you write trigonometric functions in Scilab?**

In the table below the basic mathematical functions defined in Scilab are explained….Trigonometry functions.

Mathematical function | Scilab function | Mathematical formula |
---|---|---|

hyperbolic cosine | cosh(x) | \begin{equation*} \begin{split} cosh(x) = \frac{e^{2 \cdot x} + 1}{2 \cdot e^x} \end{split} \end{equation*} |

**What is exp in Scilab?**

Description. exp(X) is the (element-wise) exponential of the entries of X .

## What is polar plot in Scilab?

polarplot creates a polar coordinate plot of the angle theta versus the radius rho. theta is the angle from the x-axis to the radius vector specified in radians; rho is the length of the radius vector specified in dataspace units.

### What is the magnitude of 3 4i?

The magnitude of 3 + 4i is 5. We can calculate the magnitude of 3 + 4i using the formula for the magnitude of a complex number.
