python Programming Glossary: linspace

http://stackoverflow.com/questions/10753528/numpy-array-creating-with-a-sequence

this using scipy. The closest I am right now is this a 0.2 linspace 1 60 60 60.8 However this creates a list not an array and hence.. array. But then when I do this I get an error a array 0.2 linspace 1 60 60 60.8 ValueError setting an array element with a sequence... as the third argument the slicing notation behaves like linspace v NP.r_ .2 1 25 7j 60.8 v array 0.2 1. 5. 9. 13. 17. 21. 25...
