An automatic door at a store has a sensor in front (a0) and behind (a1). the
door opens (b0=1) when a person approaches from the front, and stays open as
long as a person is detected in front or behind. if the door is closed and a person
approaches from the behind, the door does not open. if the door is closed and a
person approaches from the front but a person is also detected behind, the door
does not open, to prevent hitting the person that is behind.

In a heat transfer course, we can derive the equation for the temperature distribution in a flat rectangular plate. in this example, we will look at a plate at steadystate with three sides being held at t1, and one side held at t2. the temperature for any location on the plate, t(x,y), can be calculated by where create a function (prob3_5) that will take inputs of vectors x and y in feet, scalar n, scalars l and w in feet and scalars t1 and t2 in degrees fahrenheit. it will output a matrix t which is the temperature of each x and y locations. t will have the number of columns equal to the number of elements in x and rows equal to the number of elements in y. though this can be done without loops (perhaps more efficiently), your program must use a nested loop.
