Study Notes
MATLAB Basics
- MATLAB was originally designed to solve linear algebra type problems.
- The 'clear' command in MATLAB is used to clear all variables from the workspace.
Variable Names in MATLAB
- A variable name in MATLAB must start with a letter.
Output Commands in MATLAB
- The purpose of 'Fprintf' and 'disp' commands in MATLAB is to display output to the screen.
- 'Fprintf' is a formatted output command, while 'disp' is a simple display command.
History of MATLAB
- The original purpose of MATLAB was to provide easy access to matrix software.
Command Window Management
- The 'clc' command in MATLAB is used to clear the command window.
Limitations of MATLAB
- MATLAB is not suitable for symbolic computations.
Meaning of MATLAB
- MATLAB stands for Matrix Laboratory.
Interpolation
- Interpolation is a method of finding an intermediate value between two known values.
- It is significant in numerical methods as it helps to approximate values between discrete data points.
Linear Interpolation
- Linear interpolation is a method of interpolation that uses a straight line to estimate an intermediate value.
- It is calculated using the following formula: y = y1 + ((x - x1) / (x2 - x1)) * (y2 - y1).
- Example: Using a table with x values 1 and 3, and corresponding y values 2 and 4, find the interpolated y value for x = 2. Answer: y = 2 + ((2 - 1) / (3 - 1)) * (4 - 2) = 3.
Interpolation in Smoothed Particle Hydrodynamics (SPH)
- In the context of SPH, interpolation is used to approximate values at intermediate points in a continuous function.
Other Interpolation Methods
- Two other interpolation methods mentioned in the text are:
- Spline interpolation
- Nearest neighbor interpolation
