How do you plot a linear equation in Matlab?

Use the linspace function to define x as a vector of 150 values between 0 and 10. Define y as cosine values of x . x = linspace(0,10,150); y = cos(5*x); Create a 2-D line plot of the cosine curve.

How do you write a quadratic equation in Matlab?

Quadratic question using the function command

1. Without using the roots command, write a function to calculate roots of the quadratic equation.
2. ax^2+bx+c.
3. Inputs to the function should be the coefficients a, b and c and output should.

Is Simulink like LabView?

Simulink is a programming based model. It is used to create a block diagram representation of a model. Then it is used to generate the code to deployed on the hardware. While on the other hand, LabView is a programming language.

How do you solve an ode equation in Simulink?

1.1Solving an ODE Simulink is a graphical environment for designing simulations of systems. As an example, we will use Simulink to solve the first order differential equation (ODE) dx dt = 2sin3t 4x.(1.1) We will also need an initial condition of the form x(t0) = x0at t = t0. For this problem we will let x(0) = 0.

How to solve the first order differential equation using Simulink?

As an example, we will use Simulink to solve the first order differential equation (ODE) dx dt = 2sin3t 4x.(1.1) We will also need an initial condition of the form x(t0) = x0at t = t0. For this problem we will let x(0) = 0. We can solve Equation (1.1) by integrating dx dt to formally obtain x(t) = Z (2sin3t 4x(t))dt.

What are the characteristics of Simulink model?

Simulink Model from ODE Equations A system of ordinary differential equations (ODE) has the following characteristics: All of the equations are ordinary differential equations. Each equation is the derivative of a dependent variable with respect to one independent variable, usually time.

How to display the output of Simulink program?

At the input of that block connect the output of the adder. Now select the sinks section from the library browser of simulink as shown in the figure below, Place this block at the output of the constraint block. This block is used to display the output of the program.
