code: public SDVariable linspace(String name, SDVariable from, SDVariable to, SDVariable length, DataType dt) {

docs: Create a new 1d array with values evenly spaced between values 'start' and 'stop'
  For example, linspace(start=3.0, stop=4.0, number=3) will generate [3.0, 3.5, 4.0]
  
  @param name   Name of the new variable
  @param from   Start value
  @param to     Stop value
  @param length Number of values to generate
  @param dt     Data type of the output array
  @return SDVariable with linearly spaced elements
