for
language keyword for loops
Description
Used to define loops. Its syntax is:
for variable=expression ,instruction, .. ,instruction,end
for variable=expression do instruction, ,instruction,end
If expression
is a matrix or a row vector, variable
takes as values the values of each column of the matrix.
A particular case uses the colon operator to create regularly
spaced row vectors, and ressemble to traditional for loop forms :
for variable=n1:step:n2, ...,end
If expression
is a list variable
takes as values the
successive entries of the list.
Warning: the number of characters used to define the body of any conditional instruction (if while for or select/case) must be limited to 16k.
Examples
// "traditional" for loops n=5; for i = 1:n, for j = 1:n, a(i,j) = 1/(i+j-1);end;end for j = 2:n-1, a(j,j) = j; end; a for j= 4:-1:1, disp(j),end // decreasing loop //loop on matrix columns for e=eye(3,3),e,end for v=a, write(6,v),end for j=1:n,v=a(:,j), write(6,v),end //loop on list entries for l=list(1,2,'example'); l,end
