# logspace

logspace(start, stop, n=50)

Construct a vector of `n` logarithmically spaced numbers from `10^start` to `10^stop`.

## Examples

``````julia> logspace(1, 3, 5)
5-element Array{Float64,1}:
10.0
31.622776601683793
100.0
316.22776601683796
1000.0``````
1. Generate logarithmically spaced numbers:

``````julia> logspace(0, 2, 4)
4-element Array{Float64,1}:
1.0
10.0
100.0
1000.0``````

This example generates an array of 4 logarithmically spaced numbers ranging from 10^0 to 10^2.

2. Create a plot with logarithmic axis:

``````using Plots

# Generate logarithmically spaced numbers
x = logspace(-2, 2, 100)

# Create y-values using a function
y = sin.(x)

# Plot using logarithmic x-axis
plot(x, y, xaxis=:log)``````

In this example, `logspace` is used to generate logarithmically spaced x-values for a plot with a logarithmic x-axis.

3. Specify the number of elements in the output:
``````julia> logspace(1, 3, 3)
3-element Array{Float64,1}:
10.0
100.0
1000.0``````

It generates an array with 3 logarithmically spaced numbers.

Common mistake example:

``````julia> logspace(3, 1, 5)
ERROR: DomainError with -3.0:
"start = 3 > stop = 1"``````

In this example, the `start` value is greater than the `stop` value, resulting in a `DomainError`. Ensure that the `start` value is less than the `stop` value when using `logspace`.
