Results for: "remove_const"

Returns true if this is an orthogonal matrix Raises an error if matrix is not square.

Returns true if this is a permutation matrix Raises an error if matrix is not square.

Returns a new matrix resulting by stacking horizontally the receiver with the given matrices

x = Matrix[[1, 2], [3, 4]]
y = Matrix[[5, 6], [7, 8]]
x.hstack(y) # => Matrix[[1, 2, 5, 6], [3, 4, 7, 8]]

Returns the transpose of the matrix.

Matrix[[1,2], [3,4], [5,6]]
  => 1 2
     3 4
     5 6
Matrix[[1,2], [3,4], [5,6]].transpose
  => 1 3 5
     2 4 6

Returns a new matrix resulting by stacking vertically the receiver with the given matrices

x = Matrix[[1, 2], [3, 4]]
y = Matrix[[5, 6], [7, 8]]
x.vstack(y) # => Matrix[[1, 2], [3, 4], [5, 6], [7, 8]]

The coerce method provides support for Ruby type coercion. This coercion mechanism is used by Ruby to handle mixed-type numeric operations: it is intended to find a compatible common type between the two operands of the operator. See also Numeric#coerce.

Overrides Object#inspect

Collects (as in Enumerable#collect) over the elements of this vector and v in conjunction.

Like Array#collect.

Overrides Object#inspect

Add option switch and handler. See make_switch for an explanation of parameters.

Completes shortened long style option switch and returns pair of canonical switch and switch descriptor OptionParser::Switch.

typ

Searching table.

opt

Searching key.

icase

Search case insensitive if true.

pat

Optional pattern for completion.

Parses environment variable env or its uppercase with splitting like a shell.

env defaults to the basename of the program.

Returns a printable version of mtch.

puts /.$/.match("foo").inspect
#=> #<MatchData "o">

puts /(.)(.)(.)/.match("foo").inspect
#=> #<MatchData "foo" 1:"f" 2:"o" 3:"o">

puts /(.)(.)?(.)/.match("fo").inspect
#=> #<MatchData "fo" 1:"f" 2:nil 3:"o">

puts /(?<foo>.)(?<bar>.)(?<baz>.)/.match("hoge").inspect
#=> #<MatchData "hog" foo:"h" bar:"o" baz:"g">

Returns a frozen copy of the string passed in to match.

m = /(.)(.)(\d+)(\d)/.match("THX1138.")
m.string   #=> "THX1138."

Increases left margin after newline with indent for line breaks added in the block.

Ends the current PStore#transaction, committing any changes to the data store immediately.

Example:

require "pstore"

store = PStore.new("data_file.pstore")
store.transaction do  # begin transaction
  # load some data into the store...
  store[:one] = 1
  store[:two] = 2

  store.commit        # end transaction here, committing changes

  store[:three] = 3   # this change is never reached
end

WARNING: This method is only valid in a PStore#transaction. It will raise PStore::Error if called at any other time.

The content of the TempIO as a String.

Replaces the elements with ones returned by collect(). Returns an enumerator if no block is given.

Returns a string containing a human-readable representation of the set (“#<Set: {element1, element2, …}>”).
