g5c3p087x05 (element by element operations): pp72-74 of Gilat. In particular,
when you wish to multiply or divide the elements of one vector/matrix by the
corresponding elements of another vector/matrix, or when you want to raise all
the elements to a power, you MUST place a "." in front of the *, /, or ^
symbol. Refer to the last two examples on p74. To create the table of values,
see the example on pp85-86 (paying particular attention to the last command of
the code).
g5c3p093x30 (operations on matrices): remind yourself how to create a matrix
(p39) and how to transpose a matrix (p41). Here the multiplications ARE matrix
multiplication, so no dot is needed.
g5c3p094x33: (solving equations with matrices): Remind yourself how to write a
system of equations in matrix form (p68) and use inverses (p69) or left-division of
matrices (p70). There is a great example on pp71-72. NOTE that this example
also does NOT use element-by-element operations!
s517x48: (ezplot, int) Use the techniques of symbolic variables (from Lab 2) to
plot the function (f(x)=1/sqrt(x-3)) and find the area. NOTE that MATLAB handles
the improper integral automatically!
s547x17: (diff, int) Define t as a symbolic variable, then follow the steps done by
hand (differentiate x and y, then integrate sqrt(dx^2+dy^2). The resulting integral
will (likely) make no sense to the students, so keep in mind the "double"
command (p352).
Also, Please practice the appropriate Maplets over techniques of integration for
this week.
