get_y_grid {stochLAB}

Grid of vertical distances from points in the rotor circle to its horizontal axis

Description

Taking the center of the rotor circle as the origin, get_y_grid generates a grid of vertical distances y (by yinc increments) from the x-axis to the outer edge of the rotor circle, across width intervals x (by xinc increments) between the center and maximum rotor width.

Returned grid represents the left-half of the rotor's circle.

Distances are expressed as proportion of rotor radius (i.e. y is dimensionless).

Usage

get_y_grid(x_grid, yinc = 0.05)

Arguments

x_grid

A 2D array, with horizontal distances from the rotor's vertical axis, expressed as the proportion of rotor radius, for the left-half of the rotor circle area.

yinc

a numeric value, the grid increment along the y-axis

Value

2D array giving a grid of vertical distances y from the rotor's horizontal axis, expressed as the proportion of rotor radius, for the left-half of the rotor circle area. Negative values represent distances from the bottom half of the rotor circle.

Examples

 x_grid <- get_x_grid(yinc=0.05, xinc=0.05)
 get_y_grid(x_grid,yinc=0.05)
