how to solve a equation

I have a cell array,its elements are all of expression with symbol variables a{i,j}.

for example

cell array:f{n},

*f{1} = 3*b{3,5}*b{1,2} + 4*b{2,2} + ...+b{i,j},

f{2} = 4*b{3,5} + 4*b{6,2}*b{1,1} + ...+, ;

f{n} = b{2,3} + b{7,8} +;

f{n} = 0;*

I know every .expression of f{i},

if I use fsolve function,I have to display all equations,for large i, it is impractical. so is there any other method to get every b{i,j}'s value ,

 can i use fsolve like these fsolve(f);

thank you!!

I do not understand what you mean by "I have to display all equations" ?

I dont't want to write down every expressions,

for example,the number of equation exceeds 100

[Walter Roberson]

What form do you have them available in?

You should be using vectorized commands to generate f, not scalar expressions. For example, if I had equations

 f(1)=x(1)+1
 f(2)=x(2)+2
 f(3)=x(3)+3
...
 f(N)=x(N)+N

I would generate f in the single statement,

 f=x+1:length(x)

regardless of the size of N.

thank you for answer.

I mean I had already get every expression of f{i},and I want to solve these equations.

for example use fsolve function,but this means I have to write every equation,and the

number of f{i} is over 100;I don't want write down every equation,how can I solve these

equations?

[Matt J]

but this means I have to write every equation,

No, I already told you that you don't have to. You must look for an alternative matrix/vector valued way of expressing f.

Also, if you already "get every expression", it means you've already written them down, or that you have them in some sort of executable form.
