end
Terminatefor, while, switch, and if statements or indicate last index
while expression % (or if or for)
statements
end
B = A(index:end,index)
end is used to terminate for, while, switch, and if statements. Without an end statement, for, while, switch, and if wait for further input. Each end is paired with the closest previous unpaired for, while, switch, or if and serves to delimit its scope.
end command also serves as the last index in an indexing expression. In that context, end = (size(x,k)) when used as part of the kth index.
end used with for and if. Indentation provides easier readability.
for i = 1:n
if a(i) == 0
a(i) = a(i) + 2;
end
end
Here, end is used in an indexing expression:
A = rand(5,4) B = A(end,2:end)In this example,
B is a 1-by-3 vector equal to [A(5,2) A(5,3) A(5,4)].
break Break out of flow control structures
for Repeat statements a specific number of times
if Conditionally execute statements
return Return to the invoking function
switch Switch among several cases based on expression
while Repeat statements an indefinite number of times
