Substituting value from table into equation

If i have value in table form and equation

a={1 2; 3 4; 5 6}, where column 1=x , column 2=y

c=(exp(2*x)/100)+((y^3)/10)

how can i get value x and y, and substitute into the equation, and obtain the answer for individual set, then put it into matrix form?

Thank you

hi,

You extract the values like the following :

a=(1:10)'*(1:10);  % a contains 10 lines and 10 columns,the first column is x  
%and the second one is y :
% Two ways :

C1=exp((2*a(:,1))./100)+((a(:,2).^3)/10);

% or :

x=a(:,1);
y=a(:,2);
C2=exp(2*x./100)+((y.^3)/10);C2=exp(2*x./100)+((y.^3)/10);

You put the result in matrix :

 N=10; % depends on your operations 
 C=zeros(10,N);
 C(:,1)=C1; % or C2 and so on,
