Function log 

pub fn log<T: GpuFloat>(
    handle: &BlasHandle,
    n: u32,
    input: &DeviceBuffer<T>,
    output: &mut DeviceBuffer<T>,
) -> BlasResult<()>

Computes the natural logarithm element-wise: output[i] = ln(input[i]).

Arguments

• handle – BLAS handle.
• n – number of elements.
• input – input device buffer.
• output – output device buffer.

Errors

Returns BlasError on buffer validation or kernel launch failure.
