/**
* Fills a one-dimensional single-precision floating-point ndarray with logarithmically spaced values over a specified interval.
*
* ## Notes
*
* - The function expects the following ndarrays:
*
* - a one-dimensional input ndarray.
* - a zero-dimensional ndarray specifying the base of the logarithmic scale.
* - a zero-dimensional ndarray specifying the exponent of the starting value.
* - a zero-dimensional ndarray specifying the exponent of the final value.
* - a zero-dimensional ndarray specifying whether to include the `base^stop` value when writing values to the input ndarray.
*
* @param {ArrayLikeObject<Object>} arrays - array-like object containing ndarrays
* @returns {ndarray} input ndarray
*
* @example
* var Float32Vector = require( '@stdlib/ndarray/vector/float32' );
* var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
*
* var x = new Float32Vector( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );
*
* var base = scalar2ndarray( 10.0, {
* 'dtype': 'float32'
* });
*
* var strt = scalar2ndarray( 0.0, {
* 'dtype': 'float32'
* });
*
* var stp = scalar2ndarray( 5.0, {
* 'dtype': 'float32'
* });
*
* var endpoint = scalar2ndarray( true, {
* 'dtype': 'bool'
* });
*
* var out = slogspace( [ x, base, strt, stp, endpoint ] );
* // returns <ndarray>[ 1.0, 10.0, 100.0, 1000.0, 10000.0, 100000.0 ]
