Matlab Function and Input

Question

function area = traparea(a,b,h)
%  traparea(a,b,h)   Computes the area of a trapezoid given
%                    the dimensions a, b and h, where a and b
%                    are the lengths of the parallel sides and
%                    h is the distance between these sides

%  Compute the area, but suppress printing of the result
area = 0.5*(a+b)*h;

This is just an example. I would like to know how to declare the values suppose a=5,b=4,h=8 in a seperate .m file and calling it into original function ie, traparea, using .in statement? for example .in a=5 like that Please help

Not clue what a ".in statement" is. You just call the function from the m-file: area = traparea(5,4,8);. — TroyHaskin

If I understand, you want to create a script file. Create a filename called "myscript.m" (pick any name you like), and place it in the same folder as "traparea.m" is located. Then, in the file "myscript.m", put the following:

a = 5;
b = 4;
h = 8;
result = traparea(a,b,h)   % this is one way to show the result
fprintf('my result is %f\n', result);  % this is another way to display the result

Once you have created the two files "myscript.m", and "traparea.m", you just type "myscript" at the command line.

Much thankful to you. Much useful comment. If you don't mind shall I ask one more question? Is there any way to get the same result using internal data structures like in. ?
