findstr returns
all rows of x that contain at least one match
for pattern.
If called with three return values, findstr
returns the row and column indices in x
where matches were found, and the length of
each match. The values, R, C and M
are integer column vectors with row dimension equal
to the number of matches found in x.
findstr({"hip", "hipe", "hills", "hope", "Hippy"}, "[hH].p+")
O-Matrix will respond
hip
hipe
hope
Hippy
If you continue the example by entering
S = {"hip", "hipe", "hills", "hope", "Hippy"}
[R,C,M]=findstr(S, "[hH].p+")
print [R, C, M]
O-Matrix will return,
{
[ 1 , 1 , 3 ]
[ 2 , 1 , 3 ]
[ 4 , 1 , 3 ]
[ 5 , 1 , 4 ]
}
where R contains the row indices of each match, C
contains the column indices of each match, and M
contains the length of each match.
If you continue by entering the following,
for i = 1 to rowdim(R) begin
print S.blk( R(i), C(i), 1, M(i) )
end
O-Matrix will print each of the matched strings,
hip
hip
hop
Hipp
