## Can you use MATLAB to solve differential equations?

You can solve the differential equation by using MATLAB® numerical solver, such as ode45 . For more information, see Solve a Second-Order Differential Equation Numerically.

**How do you solve differential equations using Laplace in MATLAB?**

Solve Equations Compute the Laplace transform of eqn1 and eqn2 . The function solve solves only for symbolic variables. Therefore, to use solve , first substitute laplace(I1(t),t,s) and laplace(Q(t),t,s) with the variables I1_LT and Q_LT . Solve the equations for I1_LT and Q_LT .

**What is the MATLAB command for solving the differential equation?**

### Can we solve PDE in MATLAB?

What Types of PDEs Can You Solve with MATLAB? The MATLAB® PDE solver pdepe solves initial-boundary value problems for systems of PDEs in one spatial variable x and time t. You can think of these as ODEs of one variable that also change with respect to time.

**How do you code an equation in MATLAB?**

To insert an equation interactively:

- Go to the Insert tab and click Equation. A blank equation appears.
- Build your equation by selecting symbols, structures, and matrices from the options displayed in the Equation tab.
- Format your equation using the options available in the Text section.

**What is laplace in MATLAB?**

laplace( f ) returns the Laplace Transform of f . By default, the independent variable is t and the transformation variable is s . example. laplace( f , transVar ) uses the transformation variable transVar instead of s . example.

## What is Dirac in MATLAB?

dirac returns floating-point results for numeric arguments that are not symbolic objects. dirac acts element-wise on nonscalar inputs. The input arguments x and n must be vectors or matrices of the same size, or else one of them must be a scalar.

**Can MATLAB do inverse Laplace transform?**

ilaplace( F ) returns the Inverse Laplace Transform of F . By default, the independent variable is s and the transformation variable is t . If F does not contain s , ilaplace uses the function symvar . ilaplace( F , transVar ) uses the transformation variable transVar instead of t .

**How do you simulate equations in MATLAB?**

Build the Model

- Add a Math Function block and connect the input to signal B . Set the Function parameter to square .
- Connect the output from the Math Function block to a Gain block. Set the Gain parameter to 3e7 .
- Continue to add the remaining differential equation terms to your model.
