Function handling problem in loop

Dear Researcher.

Might be it will be a silly question for you but i am stuck at this point . I have a two function which calulates minimum and max values as given below:

function out=fns1(X)

x1=X(:,1);

x2=X(:,2);

x3=X(:,3);

x4=X(:,4);

x5=X(:,5);

x6=X(:,6);

x7=X(:,7);

x8=X(:,8);

x9=X(:,9);

x10=X(:,10);

out = 5.16.*x1+5.12.*x2+4.89.*x3+4.79.*x4+4.99.*x5+5.45.*x6+4.65.*x7+4.99.*x8+5.45.*x9+5.5.*x10+3;

and the other is :

function out= fns(X)

x1=X(:,1);

x2=X(:,2);

x3=X(:,3);

x4=X(:,4);

x5=X(:,5);

x6=X(:,6);

x7=X(:,7);

x8=X(:,8);

x9=X(:,9);

x10=X(:,10);

fx =5.16.*x1+5.12.*x2+4.89.*x3+4.79.*x4+4.99.*x5+5.45.*x6+4.65.*x7+4.99.*x8+5.45.*x9+5.5.*x10+3;

for i=1:size(fx,1)

if fx(i,:)>=0

fit(i,:)=1./(1+fx(i,:));

elseif fx(i,:)<0

fit(i,:)=1+abs(fx(i,:));

end

end

out=fit;

I want to use function with different values of x1 x2 to x10. These values have in text form i want to know how i can get these values and use them in function for each iteraion just like that

for i=1:100

function out=fns1(X)

x1(i)=X(:,1);

x2(i)=X(:,2);

x3(i)=X(:,3);

x4(i)=X(:,4);

x5(i)=X(:,5);

x6(i)=X(:,6);

x7(i)=X(:,7);

x8(i)=X(:,8);

x9(i)=X(:,9);

x10(i)=X(:,10);

out (i)= 5.16.*x1+5.12.*x2+4.89.*x3+4.79.*x4+4.99.*x5+5.45.*x6+4.65.*x7+4.99.*x8+5.45.*x9+5.5.*x10+3;

help me out plz.

Thans in advance

Try

doc str2num

to convert from text to numeric.

Also, you might find it easier to define:

k = [5.16 5.12 4.89 4.79 4.99 5.45 4.65 4.99 5.45 5.5]';

and then calculate

fx = X*k+3; 

etc.

Dear Steve

5.16 5.12 4.89 4.79 4.99 5.45 4.65 4.99 5.45 5.5 these values also changes with respect to loop actually i want to use a look for value 1:100 so that at each iteration x1 to x10 values changes with respect to loop index

"...these values also changes with respect to loop actually i want to use a look for value 1:100 so that at each iteration x1 to x10 values changes with respect to loop index"

Put all of the values into a 100x10 matrix. Inside the loop use indexing to access each row.

Don't make this more complex than it needs to be.
