Usage

# S3 method for class '`2d_Isingland`'
calculate_barrier(l, ...)

# S3 method for class '`2d_Isingland_matrix`'
calculate_barrier(l, ...)

# S3 method for class 'barrier_2d_Isingland'
print(x, simplify = FALSE, ...)

# S3 method for class 'barrier_2d_Isingland'
summary(object, ...)

# S3 method for class 'barrier_2d_Isingland_matrix'
summary(object, ...)

Arguments

l

An Isingland object constructed with make_2d_Isingland() or make_2d_Isingland_matrix().

...

Not in use.

x

a result of the default method of summary().

simplify

Print a simplified version of the output? Default is FALSE.

object

an object for which a summary is desired.

Value

A barrier_Isingland object that contains the following components:

• shape A character describing the shape of the landscape.

• local_min_start,local_min_end,saddle_point The positions of the two local minimums and the saddle point, described each by a list containing:

  • U The potential value.

  • location

    • x_index The row index in get_dist(l).

    • x_value The number of active nodes.

• delta_U_start,delta_U_end The barrier heights for both sides.

Functions

• summary(barrier_2d_Isingland): Return a vector of barrier heights.

• summary(barrier_2d_Isingland_matrix): Return a tibble of barrier heights and conditions.
