FreeMAT

experimenting with freemat

exercise 1
plotting sine and cosine functions

Assignment 1

-15=30i1-10i2
-7=-10i1+15i2

R =
  30 -10
 -10  15
--> V=[-15;-7]
V =
 -15
  -7
--> I=inv(R)*V
I =
   -0.8429
   -1.0286
I2-I1=I3
--> -1.0286-(-.8429)
ans =
   -0.1857

Assignment 1 circuit A vs B
1.

circuit A will have the lowest output sooner

2.

this time A has the higher output sooner

Assignment 2

yes the theoretical and the freemat outputs match, here is the picture

in conclusion I have decided that freemat is a very useful tool if you know what you are doing, and it appears to be simple enough to use that I will definitely use it in the future.
