define a matrix named a=b*a that stores the value of the product between vectors 𝐛 and � in matlab

Assuming that a and b are vectors of the same size, you can define the matrix a as the product between b and a using the matrix multiplication operator * in Matlab as follows:

main.m
a = b * a;
11 chars
2 lines

This will compute the product between the elements of vector b and vector a and store the resulting matrix in a.

Note that the order of the multiplication matters, since matrix multiplication is not commutative. In this case, we're multiplying b by a, which means that the number of columns in b must match the number of rows in a.

Also, be careful when using the assignment operator = to avoid overwriting existing variables unintentionally.
