for variable = expression
statements
end
The columns of thefor variable = expression
statement
...
statement
end
expression
are stored one at a time in the variable while the following statements, up to the end
, are executed.
In practice, the expression
is almost always of the form scalar
: scalar
, in which case its columns are simply scalars.
The scope of the for
statement is always terminated with a matching end
.
n
has already been assigned a value. Create the Hilbert matrix, using zeros
to preallocate the matrix to conserve memory:
Stepa = zeros(n,n) % Preallocate matrix
for i = 1:n
for j = 1:n
a(i,j) = 1/(i+j -1);
end
end
s
with increments of -0.1
Successively setfor s = 1.0: -0.1: 0.0,...,
end
e
to the unit n
-vectors:
The linefor e = eye(n),...,
end
has the same effect asfor V = A,...,
end
exceptfor j = 1:n,
V = A(:,j);..., end
j
is also set here.
