MATLAB Function Reference Volume 1: A - E - Bad Request

Examples The file buggy, used in these examples, consists of three lines.
function z = buggy(x)
n = length(x);
z = (1:n)./x;
Example 1 – Stop at First Executable Line
The statements
dbstop in buggy
buggy(2:5)
stop execution at the first executable line in buggy
n = length(x);
The function
dbstep
advances to the next line, at which point, you can examine the value of n.
dbstop
Example 2 – Stop if Error
Because buggy only works on vectors, it produces an error if the input x is a full
matrix. The statements
dbstop if error
buggy(magic(3))
produce
??? Error using ==> ./
Matrix dimensions must agree.
Error in ==> c:\buggy.m
On line 3 ==> z = (1:n)./x;
