[xZero]

yup mines exactly the same

[m@tty]

Assignment is up..

[JinXi]

Same answer's here too, except my 4b) gives a slightly different answer( by like .000001) and 0.01 pert results in an infinite loop for some reason.... so i used 0.001.

Time to get started on the Assignment guys =D

[xZero]

so how did everyone go in the lab? the average for this week went down to 6.8

For task 2, do you have to use size or length?

[JinXi]

for the fzero on Q5, did u guys get 137.1801? Not really sure if im doing it right cause all my 3 methods gives 144. xx which is 7 degrees off.. Im quite sure my methods for roots are right so ....

For task 2, do you have to use size or length?

I used nested root,

Eg,
 for number of rows A
     for number of columns B
            multiply each element in the row of A by its corresponding element in each column in B.

Something along those lines =)


Edit: forget what i said about the fzero, realised i somehow managed to copy the code incorrectly.... :buck2:

your fzero answer is way off, it should be 144.xx

Say you defined the dimensions of a matrix as size_A = size(A)
Then does size_A(1) give you the number of rows for matrix A? Or am I missing something?

Yeah thats right, so you have to repeat the loop that number of times.

[sajib_mostofa]

So the number of times you repeat the loop depends on the number inside the bracket of size_A(x)?

Yeah its the same as when u multiply a matrix A * B by hand, you take the 1st row of A(loop here), multiply it by columns B from left to right(another loop here), then you go to the 2nd row of A, repeat the process.

For task 3 , do we have to make the graph animate?

[taiga]

Hey guys, I hate computing

[JinXi]

For task 3 , do we have to make the graph animate?

highly doubt it. I just graphed the initial graph to let the user estimate, then graphed the result.

However if you want some animations go for it =D they wont complain. I did some animations for the last lab and the demonstrators liked it, but he said it wasn't neccessary, so screw it.

Hey guys, I hate computing

Ur gna think im weird but i kinda like playing with Matlab

Not sure if that'll stay once I start the assignment

[sajib_mostofa]

Matlab could be fun if I bloody knew how to use it properly...
