What is logarithmic spacing?

For example, the numbers 10, 100, 1000, and 10000 are equally spaced on a log scale, because their numbers of digits is going up by 1 each time: 2, 3, 4, and 5 digits. In this way, adding two digits multiplies the quantity measured on the log scale by a factor of 100.

Why would you use a logarithmic scale?

Logarithmic scales are useful when the data you are displaying is much less or much more than the rest of the data or when the percentage differences between values are important. You can specify whether to use a logarithmic scale, if the values in the chart cover a very large range.

How is Logspace calculated?

The function LogSpace generates a logarithmic number series based on 10, with a specified number of elements. The parameters Start and Stop set the values for the first and last element. The intermediate values are calculated from the number of elements.

How does Logspace work?

The logspace function generates logarithmically spaced vectors. Especially useful for creating frequency vectors, it is a logarithmic equivalent of linspace and the ":" or colon operator. y = logspace(a,b) generates a row vector y of 50 logarithmically spaced points between decades 10^a and 10^b .
