myvec.mygrid¶

myvec.mygrid(u, v, x=None, y=None, rowstep=16, colstep=16, interpolation='lanczos')[source]¶

Plot a 2D vector field as deformed grid on a 2D lattice

Parameters:

Parameters:	u : NumPy 2darray x components of the vector field w(x,y) = (u(x,y),v(x,y)). Note that u has to be a 2D array of the same dimension as v. v : NumPy 2darray y components of the vector field w(x,y) = (u(x,y),v(x,y)). Note that v has to be a 2D array of the same dimension as u. x : NumPy 2darray 2D grid array of x-values on the domain of w(x,y). By default it is assumed that w is defined on [1,N]-by-[1,N] y : NumPy 2darray 2D grid array of y-values on the domain of w(x,y). By default it is assumed that w is defined on [1,N]-by-[1,N] rowstep : int Array row stride (step size) used to generate the grid. Default value is 16. colstep : int Array column stride (step size) used to generate the grid. Default value is 16. interpolation : str Interpolation to be used for plotting. Default value is “lanczos”. Recommended other values are “bilinear” or “nearest”. See Matplotlib’s imshow-documentation for details.
Returns:	Nothing : None

u : NumPy 2darray

x components of the vector field w(x,y) = (u(x,y),v(x,y)). Note that u has to be a 2D array of the same dimension as v.

v : NumPy 2darray

y components of the vector field w(x,y) = (u(x,y),v(x,y)). Note that v has to be a 2D array of the same dimension as u.

x : NumPy 2darray

2D grid array of x-values on the domain of w(x,y). By default it is assumed that w is defined on [1,N]-by-[1,N]

y : NumPy 2darray

2D grid array of y-values on the domain of w(x,y). By default it is assumed that w is defined on [1,N]-by-[1,N]

rowstep : int

Array row stride (step size) used to generate the grid. Default value is 16.

colstep : int

Array column stride (step size) used to generate the grid. Default value is 16.

interpolation : str

Interpolation to be used for plotting. Default value is “lanczos”. Recommended other values are “bilinear” or “nearest”. See Matplotlib’s imshow-documentation for details.

Returns:

Nothing : None
