Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
ode15i.m, ode15s.m: Follow Octave coding conventions. * ode15i.m, ode15s.m: Use double quotes instead of single quotes. Wrap lines > 80 characters. Simplify calls to error() by placing name of field in error string rather than using '%s'. Use space between function name and opening parenthesis. End fail() lines with semicolon.
