How can I write a loop that performs a function to each element in a matrix / array?

How can I create a code that can preforms a function to each value in a matrix?

Below is Reference:

function yi = TableLook(x, y, xx)
n = length(x);
if xx < x(1) || xx > x(n)
 error('Interpolation outside range')
end
% sequential search
i = 1;
while(1)
 if xx <= x(i + 1), break, end
 i = i + 1;
end
% linear interpolation
yi = y(i) + (y(i+1)-y(i))/(x(i+1)-x(i))*(xx-x(i));

x is equal to e. and e=linspace(0,1,1668)

y is equal to X. *I have predetermined the X values on my end

I am trying to create a code that calls Table look and inputs a value from 0-1.

For example I would like my code to use this arrangment of values [0.01 0.02 0.03].

I am new to MATLAB and have been struggling with this. Please help.

%You can call the function in for loop

%I don't get what you are trying to do just some guess

input=[0.01 0.02 0.03];

for i=1:length(x)

for j=1:length(y)

result(i,j)=TableLook(x,table(i,j), input);

end

end

If you intend to apply your function to elements of an array vector, you can use arrayfun

xx = 1; 
yi = arrayfun(@(x, y)TableLook(x, y, xx), linspace(0, 1, 1668), linspace(0, 1, 1668));
