Homework Statement
Hi, I'm doing nodal analysis and I end up with 3-5 equations that need solving simultaneously. I have been sticking them in mathematica and letting it do its thing but I need to be able to do it on my 89 too.
The trouble is that there not in a matrix friendly form - - - something like this:
[tex] 0=(v_1-10)/4700+v_1/10000+(v_1-v_2)/1000 [/tex]
[tex] 0=(v_2-v_1)/1000+(v_2-v_4)/470+(v_2- v_4)/1000 [/tex]
[tex] 0=(v_4-v_2)/1000+(v_4-v_2)/470+v_4/10000+(v_4-5)/10000 [/tex]
Can someone help me find a simple way of solving these
Thanks
