So, inside eval() command, turns the strings inside it to operators. This is an another versatile use of eval() command in Matlab®. So, for each value of ‘a’ for each loop, these three matrices will create three values for each x1, x2… To obtain x1, x2… we typed ‘x’ inside quotes, and for coefficients, we used the num2str() command to type each step number which are the values of ‘a’ in each step, as strings as coefficients.Īnd inside quotes, we created our matrix in each element has a function created by the variable of ‘a’. And all the new three values for each variable will take new values according to the functions inside the eval() command.

In this code here, we want to create 10 variables that will take the names x1, x2… up to x10. In the command window of Matlab®, we created a very basic for-end loop. For each step of the for-end loop, three new values will be calculated with the eval() command.

This is an another example about the use of eval() command in Matlab®. ‘b’ vector will take the new values of ‘a’ according to the function inside it. We typed a function in eval() command inside quotes, in which the variable is ‘a’. ‘a’ is a vector and this vector has ten elements inside it, starting from 1 to 10. > a = 1:10 Īs you see in the above example, you can use the eval() command but typing functions inside it.

YOU CAN LEARN Matlab® IN MECHANICAL BASE Click And Start To Learn Matlab®! How To Use ‘eval()’ Command In Matlab®? Here, we show you how to use the eval() command in various examples done in the Matlab® command window. Here we discuss Introduction, syntax, Description, and Examples with code implementation.In Matlab®, eval() is a very versatile command that you can easily use for lots of purposes. The flexibility it offers becomes very useful when using functions like plot, where we might need to format the graph on the go. ‘varargin’ can be used in MATLAB when we are not sure how many arguments we might need while calling the function. We will pass different arguments from the ones passed above, to format the style of plot. In this example, we will define a function which will plot a sine wave.

Varargin will help us to pass as many arguments as we want to the plot] We will pass the number of arguments to format the style of a plot as per or requirement. In this example, we will define a function that will plot a cos wave. LearningVarargin ('extra argument', rand (3)) Now in the new command window, use the following code: m extension:ĭisp ("Input arguments passed: " + nargin)
