<div>
Actually i want to convert a 2D matrix into a vector:<br />
your example worked but I was wondering if i can do that with numpy.<br />
because later i have to calculate a - 1.<br />
and it's not working with that method.

hello i want to know how can we convert a matrix to a vector in python?<br />
<br />
in matlab if i have a matrix a = &nbsp;[[1 2 3];[4,5,6];[7,8,9]]<br />
if i use a(:)<br />
i will get :1<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;2<br />

convert matrix  to vector python

Python is a widely used general-purpose, high-level programming language. Its design philosophy emphasizes code readability, and its syntax allows programmers to express concepts in fewer lines of code than would be possible in other languages. Python supports multiple programming paradigms, including object-oriented, imperative and functional programming or procedural styles. It features a dynamic type system and automatic memory management and has a large and comprehensive set of standard libraries, including NumPy, SciPy, Django, PyQuery, and PyLibrary.
