How to Write a Function for ODE45
MatLab is a computer programming language that was used to create the ODE45 function-solving program. Users can write and map their mathematical functions in this program. Learning how to write a function using ODE45 is a complex process that requires understanding the basic steps of programming. Only use this function-writing capability if you understand how to use ODE45 on a basic level.

1
Type the word "function" and follow that with your function title. For example, write "function math" for a basic function name. Press the "Enter" key to go to a new line.
-
2
Enter the letter "t" and follow that with the type of function you want to create. Write the word "start" followed by an "=" sign. For example, if you want to create a "span" function, type "tspan=" followed by the numbers you want to include, such as "0:0.2:0.3:0.4:0.6:0.8:0.9:0."

Press the "Enter" button to go to a new line. Input your other variables by typing the "x" and "y" variables. Follow each variable by an "=" sign and include these in brackets. For example, type "y0 = [5; 8]" to set your "y0" variables to "5" and "8."

4
Add your other variables in this way and add any "plotting" you want to include. Include plotting to draw the images you want on the screen. Type "plot" followed by "(" and type your coordinates in a "x,y" format, followed by a ")." For example, this will read "plot(4,5)" if your coordinates are "4" and "5."
-
5
Press "Enter" and continue to add new plotting or function lines, as necessary. Type the phrase "t" followed by the name of the process you are running and type "end." For example, ending a "tspan" would read "tspanend."
-
6
Add any other processes you want to include, using the same format. Press "Enter" after inputting each new line of code. Type "end" when you are finished.
