, ~= - ANSNot equal to
0 (zero) is the typical computer science representation for true, while 1 (one) is the
typical computer science representation for false. - ANSFalse
A matrix with a determinant that is non-zero - ANSA matrix for which an inverse does
not exist
A stiff equation is a differential equation where some numerical solution approaches are
numerically stable unless you use extremely small step sizes. - ANSFalse
alpha( ) - ANSUsed to adjust the transparency of a graphics object
An array cannot contain multiple pieces of information. - ANSFalse
animatedline( ) - ANSCreates a line animation
Annotation axes - ANSEnables one to insert annotation objects such as lines, legends,
and text boxes onto a figure
Arithmetic and Logic Unit (ALU) - ANSPerforms mathematical operations
Array - ANSContainer for multiple pieces of orderly information
At the end of a for loop, the loop index variable keeps its most recent value. - ANSTrue
axis( ) - ANSUsed to control the axes of a plot
Bit - ANSOne 0 or 1
break - ANSUsed to cause the termination of the smallest enclosing for loop or while
loop
break and continue are "go-to" techniques that all programmers should readily use. -
ANSFalse
Built-in backslash operator approach for solving systems of linear equations -
ANSsolution = A\b
