Sure, here's how to find the first element of an array in MATLAB:
To find the first element of an array, you can use the indexing operator ([]) with an index of 1.
Here's an example code snippet that demonstrates this:
% create an example array
myArray = [3 5 7 9];
% find the first element of the array using indexing
firstElement = myArray(1);
% display the first element
disp(firstElement);
Output:
3
In this example, we created an array
[3 5 7 9] and used the indexing operator to find the first element of the array, which is 3.
