What command is used to find the inverse of a matrix?
Think of how we denote inverse in mathematics.
What command in SCILAB creates a matrix?
Think about how we define a collection of numbers.
True or False: The inverse of a singular matrix exists.
Recall what makes a matrix non-invertible.
Given matrices A = [1, 2; 3, 4] and B = [5, 6; 7, 8], determine if they are invertible, and if so, calculate A_inv and B_inv.
Check det(A) and det(B) for non-zero values.
Solve the linear equations A x = b for A = [2, 3; 4, 5] and b = [8; 18].
