The Gram-Schmidt Process

The video tutorial explains the Gram-Schmidt Process, a method to convert a set of vectors into an orthogonal or orthonormal basis. It begins with an introduction to the concept, followed by a detailed explanation of the process steps. An example is provided using vectors in R3 to demonstrate the calculations involved. Finally, the tutorial shows how to convert the orthogonal basis into an orthonormal basis, emphasizing the importance of this process in various vector spaces.

What is the primary goal of the Gram-Schmidt Process?

• To calculate eigenvalues

• To find the determinant of a matrix

• To convert a set of vectors into an orthogonal set

• To solve linear equations

In the Gram-Schmidt Process, what is the first step when given a set of basis vectors?

• Normalize all the vectors

• Find the inverse of the matrix formed by the vectors

• Set the first new vector equal to the first basis vector

• Calculate the cross product of the vectors

What operation is used to ensure each new vector is orthogonal to the previous ones in the Gram-Schmidt Process?

• Vector addition

• Subtraction of inner products

• Cross product

• Matrix multiplication

In the example provided, what is the result of the vector u2 after applying the Gram-Schmidt Process?

• (1, -1, 1)

• (1/3, 2/3, 1/3)

• (0, 1, 0)

• (1, 0, 1)

How do you convert an orthogonal basis to an orthonormal basis?

• By subtracting the mean of the vectors

• By dividing each vector by its length

• By multiplying each vector by its length

• By adding a constant to each vector
