Draw samples from a log normal distribution with specified mean, standard deviation, and array shape. A lognormal distribution results if a random variable is the product of a large number of independent, identicallydistributed variables in the same way that a normal distribution results if the variable is the sum of a large number of independent, identicallydistributed variables.
The example below shows an instance of broadcasting. Returns the standard deviation, a measure of the spread of a distribution, of the nonnan array elements. If i use less than 6 rows, the result will be correct, but as long i used more than 5 rows 6, the result will be wrong. For consistency between python 2 and python 3, well also ensure that print is.

While this could make sense for more featureful random libraries e. The following are code examples for showing how to use numpy. What this means in general is that the smaller array or scalar is broadcasted across the larger array so that they have compatible shapes. The general problem is that either matplotlib has stopped plotting masked arrays correctly or numpy has changed the way masked arrays are presented.
