zeros_like
result = zeros_like(x)
Input: x · Output: result
What it is
A vector or matrix of the same shape as x (a Vec or Mat), filled with one or zero respectively — the shape is read directly from x, so it cannot fall out of step with it.
Overloads
One call shape — this function is not overloaded.
| Code | Input | Output | Description |
result = zeros_like(x) | x vector, matrix, Vec, or Matnot documented yet | result — | Returns the same type and shape as x. |
Examples
From the documentation, and run by the build -- the output and the figure below are what the engine actually produced. Simplest first.
g = meshgrid([1, 2, 3], [1, 2])
print(g.x) # x-coordinate at every grid point
print(g.y) # y-coordinate at every grid point
M = [1, 2, 3; 4, 5, 6]
print(ones_like(M))
print(zeros_like(M))
print("row_mean={row_mean(M)} row_sum={row_sum(M)}")
output
[1, 2, 3; 1, 2, 3] [1, 1, 1; 2, 2, 2] [1, 1, 1; 1, 1, 1] [0, 0, 0; 0, 0, 0] row_mean=[2; 5] row_sum=[6; 15]
