Test if two MLX arrays are (nearly) equal

Source: R/math.R
all.equal.mlx.Rd

S3 method for all.equal following R semantics. Returns TRUE if arrays are close, or a character vector describing differences if they are not.

Usage

# S3 method for class 'equal.mlx'
all(target, current, tolerance = sqrt(.Machine$double.eps), ...)

Arguments

target, current

MLX arrays to compare

tolerance

Numeric tolerance for comparison (default: sqrt(.Machine$double.eps))

...

Additional arguments (currently ignored)

Value

Either TRUE or a character vector describing differences.

Details

This method follows R's all.equal() semantics:

  • Returns TRUE if arrays are close within tolerance

  • Returns a character vector describing differences otherwise

  • Checks dimensions/shapes before comparing values

The tolerance is converted to MLX's rtol and atol parameters:

  • rtol = tolerance

  • atol = tolerance

Examples

a <- as_mlx(c(1.0, 2.0, 3.0))
b <- as_mlx(c(1.0 + 1e-6, 2.0 + 1e-6, 3.0 + 1e-6))
all.equal(a, b)  # TRUE
#> [1] "Arrays are not all close within tolerance"

c <- as_mlx(c(1.0, 2.0, 10.0))
all.equal(a, c)  # Character vector describing difference
#> [1] "Arrays are not all close within tolerance"
