The output of the example script given above can be seen in the image below. The output can be saved to many different types of formats, including HTML, Latex, and PDF. You can also write functions which take a variable number of arguments. Matlab will run the script, and save the images which are displayed, as well as the text generated by the command line. You can define your own functions to complement those provided by MATLAB. The publish option can be found under the "Publish" tab, highlighted in the image Simple Function Documentation below. Legend('Analytical Solution','Uncorrected FFT','Corrected FFT') Title('Comparison of Corrected and Uncorrected FFT') % Take FFT and corrected FFT then compare After that, we will write our code inside the function. To define a function, we use the variable function, and then we define the outputs, the function name, and the inputs of the function. Xan = A*sqrt(2*pi)*exp(-2*pi^2*f.^2*A^2) %X(f), real part of the analytical Fourier transform of x(t) A function in Matlab consists of mainly three things output, input, and function name.

This call to inline defines the function f to be dependent on two variables, alpha and x: f inline ( 'sin (alphax)' ) f Inline function: f (alpha,x) sin (alphax) If inline does not return the desired function variables or if the function variables are in the wrong order, you can specify the desired variables explicitly with the inline. % Generate a signal with an analytical solution. % to: Why_use_fftshift(fft(fftshift(x)))_in_Matlab.pdf included in the % For a full description of why the FFT should be taken like this, refer % be multiplied by dt to have physical significance. % This function uses the "proper" fft in matlab. Thanks to Wu, Kan, the original author of this function. This is a separate script which explains the inputs, outputs, and gives an example explaining why the correction is necessary. Out_sig = fftshift(fft(ifftshift(in_sig))) This function uses a "corrected" FFT in Matlab. Datenum (MATLAB Functions) MATLAB Function Referenceonvert date and time to. The syntax for documenting your code can be found here. Here is an example of a date and time expressed in the three MATLAB formats. The publish function in Matlab can then be used to generate a help file with embedded pictures, code, links, etc. To document a function, it is often helpful to have an example script which uses your function.
