input - Request user input - MATLAB - MathWorks
x = input (prompt) displays the text in prompt and waits for the user to input a value and press the Return key. The user can enter expressions, like pi/4 or rand (3), and can use variables in the workspace. If the user presses the Return key without entering anything, then input returns an empty matrix. If the user enters an invalid expression ...
function - Declare function name, inputs, and outputs - MATLAB
Define a function in a file named calculateAverage.m that accepts an input vector, calculates the average of the values, and returns a single result. function ave = calculateAverage(x) ave = sum(x(:))/numel(x); end
tf - Transfer function model - MATLAB - MathWorks
To create the transfer function model, first specify zas a tfobject and the sample time Ts. ts = 0.1;z = tf('z',ts) z = z Sample time: 0.1 secondsDiscrete-time transfer function. Create the transfer function model using zin the rational expression.
Pass Function to Another Function - MATLAB & Simulink
Pass Function to Another Function. You can use function handles as input arguments to other functions, which are called function functions. These functions evaluate mathematical expressions over a range of values. Typical function functions include integral, quad2d, fzero, and fminbnd. For example, to find the integral of the natural log from 0 ...
plot - 2-D line plot - MATLAB - MathWorks
Call the tiledlayout function to create a 2-by-1 tiled chart layout. Call the nexttile function to create an axes object and return the object as ax1. Create the top plot by passing ax1 to the plot function. Add a title and y-axis label to the plot by passing the axes to the title and ylabel functions. Repeat the process to create the bottom plot.
step - Step response of dynamic system - MATLAB - MathWorks
Description. step computes the step response to a step change in input value from U to U + dU after td time units. Here, t0 is the simulation start time. td is the step delay. U is the baseline input value or bias. dU is the step amplitude. By default, the function applies step for t0 …
ginput - Identify axes coordinates - MATLAB - MathWorks
Description. [x,y] = ginput(n) allows you to identify the coordinates of n points within Cartesian, polar, or geographic axes. To choose a point, move your cursor to the desired location and press either a mouse button or a key on the keyboard. Press the Return key to stop before all n points are selected. MATLAB ® returns the coordinates of ...
filter - 1-D digital filter - MATLAB - MathWorks
rng default%initialize random number generator x = rand (2,15); Define the numerator and denominator coefficients for the rational transfer function. b = 1; a = [1 -0.2]; Apply the transfer function along the second dimension of x and return the 1-D digital filter of each row.
arrayfun - Apply function to each element of array - MATLAB
Function to apply to the elements of the input arrays, specified as a function handle. func can correspond to more than one function file and therefore can represent a set of overloaded functions. In these cases, MATLAB ® determines which function to call based on the class of the input arguments.
varargin - Variable-length input argument list - MATLAB
Description. varargin is an input variable in a function definition statement that enables the function to accept any number of input arguments. Specify varargin by using lowercase characters. After any explicitly declared inputs, include varargin as the last input argument. When the function executes, varargin is a 1-by- N cell array, where N ...
