Arguments

VariableNames

・Alphanumeric characters and underscores (_) can be used for variable names.
・You cannot use numbers at the beginning.

Expression

・The result of the expression becomes the initial value of the variable.
・If the expression is not specified, :Int type zero, #:Real type zero, $:empty string is set as the initial value by the type symbol (/#/$) at the end of the variable name.
・If the expression is not specified and the variable name has no type symbol, the default numeric type zero is set as the initial value.

・If a 2D array is specified for both the copy destination and the copy source, the number of channels (number of elements in the first dimension) must be the same.
・When the copy destination is 2D and the copy source is a 1D array, the copy source data is copied to all channels of the copy destination in the same way.
・Operation is not guaranteed if the copy destination and copy source are the same array.
