Any matlab users?

I need some help with this matlab lab i am working on and am wondering if anyone could help.

Exercise 1: Write an m-file to solve the set of simultaneous linear equations for the mass balance that you wrote out for prelab. In the m-file, first input from the user the matrix A, then d. Find the inverse of A, and multiply it times d for the solution. Then find the solution by using the special operator (\). Print out matrix A, d and the solution. You should use the formatted print statement fprintf. What amounts of each material are required to make the stainless steel?

The data is:

Looking in the ASM handbook, you find that AISI 304 is a high-chromium, low-carbon steel with the composition: 17.5%Cr, 8.5%Ni, 0.5%Mn, 0.2%C, and 73.3%Fe. Talking to the stock room supervisor you find that the following materials are available:

Alloy scrap (68.0%Cr, 20.0%Ni, 2.0%Mn, 0.2%C, and 9.8%Fe)

Ferrochrome (75.0%Cr, 0.1%Mn, 2.0%C, and 22.9%Fe)

Pure Nickel (99.8%Ni, 0.1%Mn, and 0.1%Fe)

Pure Iron (0.1%Mn, 0.1%C, and 99.8%Fe)

Pure Graphite (99.9%C, and 0.1%Fe)

whats a matlab? drLEGENDARY

I only know basic matlab stuff, I have to look stuf up everytime I use it.

LOL I just noticed all the people giving math advice. hilarious.

my coding is done almost entirely in matlab. i work with it daily. whats the question

Yeah, he/she is talking about http://mymathlab.com/. I know you are are all trampling his/her feelings and making fun of his typo but yeah.

Yeah buddy. I love it due to all the build in math formulas, however I find Mathematica more useful at times despite it's complexities.shakmaster13

Think you could help me out im really in need of help.

lol @people who have no idea what MATLAB is so instead of taking 3 seconds to google search it and enlighten themselves they just assume the OP doesnt know what he's talking about....WTF

anyways its actually a pretty nice program. Its a very useful tool for engineering particularly chemical and biomedical. And judging by the OP's problem I say there's a really good chance hes either studying ChemE or Material Science.

I'm actually a freshman doing undecided engineering and three weeks into class and this is what they are having us do smh, any help any1?

Personally, I thought he meant meth lab... Just when I thought I might be of some assistance. :(

Keep telling urself that :cool:

Actually im all finished even thought none of you guys were of any help :P. I was just panicking because i have the worst professor who refuses to help anyone and sucks at teaching but its all okay now. And for those who dont know what matlab is i like to think of it and using program that turns the user into a calculator himself.
