%Create the coefficient matrix A.

%Create the column matrix b of constants. Remember, to create the column matrix, the rows are separated

%by semicolons.

%Create the augmented matrix [A | b|. Store this augmented matrix in Ab.

%Use the rref() command to reduce the augmented matrix. Store the reduced matrix in rowreducedAb, and

%store the pivot variables in pivotvarsAb.

%Warning: Look carefully at the reduced augmented matrix. If one of the pivot columns is the rightmost

%column, the system of linear equation has no solution and no further analysis is possible.

%Do you run into any difficulties? Explain what is happening as a comment in your code.

%Use the size command to find the number of variables in the system of linear equations. Store this number

%in numvars.

%Use the size command to find the number of pivot variables. Store this number in numpivotvars.

%Use subtraction to find the number of free variables in the solution to the system of linear equations.

%Store this number in numfreevars.

Utilize the following linear system of equations for this activity. *1 + 3x - 213 + 2x5 = 0 2x + 61 - 513 -2x4 + 415 - 306 = -1 Kj + 5. + 3X6 = 1 "+3 +40 + 2x5 + 91 = 3
