Basic Examples  (2)

Serialize an expression:

Serialize a graphic:

Convert the serialized form back to an expression:

Scope  (7)

Options  (4)

Method  (3)

Create a packed array of integer values:

By default, BinarySerialize uses the smallest integer type that fits the data:

Serialize the packed array using a bigger integer type:

Create a packed array of real values:

Serialize the array:

Serialize the array using machine floats, trading precision for a smaller output:

Create a packed array of complex values:

Serialize the array:

Serialize the array using lower precision:

PerformanceGoal  (1)

Applications  (1)

Serialize a trained neural network:

Create a new file:

Open an output binary stream:

Write the serialized expression to the file:

Read the data from the file:

Plot the prediction of the net as a function of the input:

Properties & Relations  (4)

Possible Issues  (2)

From small expressions, PerformanceGoal->"Size" may not produce smaller outputs:

The Method parameter "PackedArrayIntegerType" must be chosen consistently with the data:

These values require 32-bit integers:

A setting of Automatic will always use a size that fits the data:
