I think it will do my job, i will try it. Thanks dear

You people are right, if you say Gaussian Elimnation is an exact one, okey still i am insisting on using expressions because in some limit to few variables involved, this huge expression will reduce to some physically interpretable expression which can't be predicted completely numerically...

Gasl, it look a bit like this "X2*X3*X4*X5*Y2*t^2 + X4*g^4*n1d*n1u*n2d*n2u*t^2 + U1*X3*X4*g^2*n1d^2*n2u*t^2 + U2*X2*X5*g^2*n1d*n2d^2*t^2 + U2*X1*X6*g^2*n2d^2*n2u*t^2 + 5.6 + U2*X1*Y2*g^2*n1d*n2d^2*t^2 + U2*X2*Y2*g^2*n1u*n2d^2*t^2 + U2*X1*g^3*n1d*n2d^2*n2u*t^2 + U2*X2*g^3*n1d*n1u*n2d^2*t^2 +...

Yes Uart, you got what i am doing. See to be more accurate every physicists tries to look for the methods which are more close to the exact. I also thought that i will use some elimination method but it is really good to use expression which is exact and this is not the only job my program do...

see gasl let me tel you what i am doing. I have eight simultaneous linear eqns for my research problem in physics. and I have calculated an expression for my desired variable using Matlab, it is a symbolic expression, which fortran can't do. Now I want that expression to be used as an input in...

Hello fortran users I, have a problem regarding values that my program produces. Let me detailed it to you. See, i have createrd a separate fortran program to calculete area under a given function i.e. it perfroms integration. When this program runs independently it gives me area of the...

thanks chiro What you wrote to me is also useful, i came to know that we can build some library to peform desired operations like reading symbolic equation from a file. And yes my equation contain countable keyboard characters including spaces they can be counted, but it is quite difficult for...

thanks uart. your reply is quite useful for me, but i am not expert of fortran as you people and i don't know how to use the parser in my program. I have downloaded it from the link provided by you, but really don't know how to use it? Can you give me an example code using this parser with...

How to read Symbolic equations from a file in fortran ?? I am working on Linux platform. I have a very big equation about two pages. I want to put that equation in a file.txt and then i want my FORTRAN program to read the equation from file.txt instead of making any function or subroutine...
