MATLAB: How can I write a code to solve an integral (from 0 to t) which only has the initial function (at t=0)

numerical integration

I want to do an integral and only have the initial function for it. Assuming a y function, it is in this way: y=integration (over the range of 0 to t) of (derivation of y with respect to distance) dt and suppose initial condition is a constant number. I am going to write it as a summation of the areas by time steps(n steps) to get the final equation as a result of integral. Do you have any suggestion that how can I make it works in MATLAB? Thanks for you time and help

This is normally called an ordinary differential equation. Your idea for solving it is effectively Euler's method, usually a poor choice if others are available.

You cannot differentiate with respect to a function in normal calculus, only with respect to a variable. Differentiating with respect to a function requires Calculus of Variations.

People often propose that you substitute a variable for the function and differentiate with respect to that. However a number of years ago I posted an example of a case where that would produce the wrong answer. Unfortunately it was long enough ago that it would be difficult to find the post.

u = @(t) double(t >= 0);
v = @(t) u(t).*u(10-t);
ezplot(v,[-10,20])

WTP?
