(atomic) operation in which all the given keys are set at the same time, and it is not possible for some given key to be updated and some other given key does not change.Parameters: ArraysReturn value: Always return OK (because Mset cannot fail)
3) Mget
Description: Returns the value of all (one or more) given key. If a specified key does not exist, then return the special value nil. Therefore, the command never fails.Parameters: Array of keyReturn value: A list of values that contain all the

modeReturned value: the list of keys that match the specified mode.
2) mset
Description: One or more key-value pairs are set at the same time. If a key with the same name exists, MSET overwrites the old value with the new value. if you do not want to overwrite the key with the same name, use the MSETNX command. MSET is an atomic operation. all given keys are set at the same time. some given keys are updated while others are not changed.Parameters: ArrayReturned value: always returns OK (because
our above independent of the same distribution assumptions. Model f with the parameter θ generates the above sample, which can be expressed
Return to the above statement "the model has been set, the parameter is unknown". What we know is that the unknown is θ, so the likelihood is defined:
In practice, the logarithm is usually obtained on both sides. The formula is as follows:
This is called the log likelihood, but the average log likelihood. What we usually call the maximum likelihood is th
Purpose:
Add a custom osgparticle instance to the scenario to simulate the dust generated when the tank model moves over the terrain.
-----------------------------Overview:
Adding particle effects can effectively improve the appearance and authenticity of the simulation program. Particle engines are generally used to simulate smoke, flame, dust, and other similar effects. To add particle effects to an OSG scenario, you can use the following classes:
