All are from this post.
What does these statement mean:
error(nargchk(5, 6, nargin));
plot(p(:,1), p(:,2), '.-'), axis equal
And what's this kinda syntax which I haven't quite often seen:
if nargin<6, steps = 36; end
A = imread(filename, fmt)
[X, map] = imread(...)
The above is in the synopsis part of imread,which seems to say the return value of matlab function depends on how it's called?Is that true?
mysql> select 0.121='0.121';
+---------------+
| 0.121='0.121' |

+---------------+
Does it hold for other database that number='number' is true?

How do I calculate the area of the image in unit of m*h?
Important UPDATE
Only the image is readily available, and I want to calculate the area programatically
bwlabel can be used to get disconnected objects in an image:
[L Ne] = bwlabel(image);
I want to make the objects connected by adding a shortest path where necessary.
How do I approach this?
The function essentially contains 2 statements:
statement1; and statement2;
If statement1 fetches some records,just return them as result;If it doesn't fetch any result,return the result of statement2.
Has anyone here tried it or is it possible?
I've been using PHP for quite a few years but never know exactly the underlying c scripts.
Is there a way to go into it?
Like :
using ::size_t; using ::fpos_t; using ::FILE;
