Hi, I have two problems. I have to calculate two equations: X = A - inv(B) * Y * inv(B) and X = Y + A' * inv(B) * A where, A, B and Y are known p*p matrices (p can be small or large, depends the situation). Matrices are quite dense, without any structure (except B being non-singular of course). Is it possible to solve X in those e...
Let's say you have a Boolean rule/expression like so (A OR B) AND (D OR E) AND F You want to convert it into as many AND only expressions as possible, like so A AND D AND F A AND E AND F B AND D AND F B AND E AND F You are just reducing the OR's so it becomes (A AND D AND F) OR (A AND E AND F) OR (...) Is there a property in Boo...
Hi, Actually I want to develop a GUI app which displays a given mathematical equation. And when you click upon a particular variable in the equation to signify that it is the unknown variable ie., to be calculated. The equation transforms itself to evaluate the required unknown variable. for eg: a = (b+c*d)/e Let us suppose that ...
Hello. What is the usual method or algorithm used to plot implicit equations of 2 variables? I am talking about equations such as, sin(x*y)*y = 20 x*x - y*y = 1 Etc. Does anyone know how Maple or Matlab do this? My target language is C#. Many thanks! ...
Hi guys, I am looking for a generic python way to manipulate text into solvable equations. For example: there may be some constants to initialize e1,e2=0.58,0.62 ma1,ma2=0.85,1.15 mw=0.8 Cpa,Cpw=1.023,4.193 dba,dbr=0.0,25.0 and a set of equations (written here for readability rather than the solver) Q=e1*ma1*Cpa*(tw1-dba) Q=ma1*Cp...
I'm trying to put together an app for fun that has a scenario where I need to figure out a probability equation for the following scenario: Suppose I have a number of attempts at something and each attempt has a success rate (known ahead of time). What are the odds after doing all those attempts that a success happens? For example ther...
I´m trying to solve this set of equations in MATLAB and I get an empty sym object: equations = {'I2B+I2EQAB=I22B+I2EQBC',... 'I2A=I2EQAB+I2EQAC+I22A',... 'I2C+I2EQBC+I2EQAC=I22C',... 'I22B=IZB+IC1B',... 'IZB=IC2B+IZBB',... 'I22C=-I2C*Z2C*YC/2+IZC',... 'IZC=IC2...
Hi guys, according to below 3 Equations x+y+z=100; x+y-z=50; x-y-z=10; how to get the value of x,y,z with java? ============================================= String equation1="x+y+z=100;"; String equation2="x+y-z=50;"; String equation3="x-y-z=10;"; int[] SolveEquations(equation1,equation2,equation3){ // to do //how to do ? } =...
I actually have an equation to make on visual basic. An exemple of it (12 = 12) AND (12>1) true and true the answer would be TRUE But for both comparison operators i must create a combo box to insert <, >, =, <=, >=, <> My problem is my program wont function because I don't know which variable to use for those... could anyo...
I am trying to add an equation in a new line. The problem is that the equation is too long for the line, and I need to break it manually. Otherwise, it just overlaps to the right column, or to the right margins (and looks ugly...). Is there a way LaTeX can brake the equation for me, so it seems nice? I'm attaching my latex code: \begin...
I'm trying to use WolframAlpha to solve for a variable. I have u(k, r) = (900-3k)r^(k-1) and s(n, r) = sum u(k, r), k=1 to n and I want to solve for r with s(5000, r) = -600000000000 I've tried various incantations, but can't seem to get it working. I can't even get s defined to evaluate it. If you care, it is to solve this pr...
Short Question: Lets say, I want to solve Project Euler problem 9 using python and some equation solving libraries. a + b + c = 1000. a2 + b2 = c2 How do you do it. Long Question: I want to solve a set of equations; linear, sometimes may be quadratic too. Not a specific problem; but often, I have been in situation I wanted to. I...
I am using Matlab and am using its solve function. I run this code and I keep getting this error [eqns,vars] = getEqns(varargin{:}) I realized I had some parens issues and fixed those but it still does work any ideas? Asp = 3.90; Arg = 12.48; Lys = 10.54; His = 6.04; Glu = 7.70; Gly = 7.50; Val = 7.44; Pro = 8.36; Ser = 6.93; ...
I have some trouble on setting of n-linear equations in matlab.I don't know how can I declare in matlab.I need matlab code for setting of n-linear equations.. ...
hi guys does anyone know about some good sources about counting complexity of recursive algorithms? somehow recurrent equation isn't really popular title for web page or what, I just couldn't google out anything reasonable... ...
I need an exponential equation with the following parameters: When x = 0, y = 153. When x = 500, y = 53. Y should increase exponentially as X approaches 0 and should decrease exponentially when X approaches 500. For some reason I can't remember how to do this. I'm sure once I see the equation (or one similar) I can figure out the rest....
I've got the following equation: a^3-4*a^2+[1 0 2;-1 4 6;-1 1 1]=0 How do I solve this in MATLAB? ...
I want to manually break a line inside $$: $$something something <breakline> something else$$ I tried "//", "\newline", and "\linebreak[]" but none work. Ideas? ...
We all know this is true: (a+b)c = ca+b*c But how to judge it in programme? ...
Gain = 255 / (1 - 10 ^ ((Refblack-Refwhite) * 0.002/0.6) ^ (Dispgamma/1.7)) Is that a computer language, it looks like c but exclusive or floats doesnt compute. Can anybody convert that to c? thanks ...
