create a vector to store and update values in matlab

In MATLAB, you can create a vector using square brackets containing comma-separated elements:

main.m
my_vector = [1, 2, 3, 4, 5];
29 chars
2 lines

Alternatively, you can use the linspace or logspace functions to create a vector with equally spaced or logarithmically spaced values, respectively.

To access a particular element of a vector, you can use indexing with round brackets ():

main.m
second_value = my_vector(2);
29 chars
2 lines

To update a particular element of a vector, you simply assign a new value to that element:

main.m
my_vector(3) = 7;
18 chars
2 lines

You can also update multiple elements in one go using indexing and assignment:

main.m
my_vector(2:4) = [10, 20, 30];
31 chars
2 lines

Note that in MATLAB, vectors are actually a special case of arrays, where the array has only one row or column. Therefore, you can use all the same array operations on vectors, such as transposing, concatenating, and reshaping.
