In the simple case where k = 2, redundancy symbols may be created by sampling different points along the line between the two original symbols. This is pictured with a simple example, called err-mail: Alice wants to send her telephone number (555629) to Bob using err-mail. Err-mail works just like e-mail, except
Format is a function in Common Lisp that can produce formatted text using a format string similar to the print format string.It provides more functionality than print, allowing the user to output numbers in various formats (including, for instance: hex, binary, octal, roman numerals, and English), apply certain format specifiers only under certain conditions, iterate over data structures ...
The channel model for the binary erasure channel showing a mapping from channel input X to channel output Y (with known erasure symbol ?The probability of erasure is . In coding theory and information theory, a binary erasure channel (BEC) is a communications channel model.
As an example a VHDL compiler may create an SVF file that is read by a tool for programming CPLDs. The SVF file is defined as an ASCII file that consists of a set of SVF statements. The maximum number of characters allowed on a line is 256, although one SVF statement can span more than one line.
The cross product operation is an example of a vector rank function because it operates on vectors, not scalars. Matrix multiplication is an example of a 2-rank function, because it operates on 2-dimensional objects (matrices). Collapse operators reduce the dimensionality of an input data array by one or more dimensions. For example, summing ...
The Geospatial Data Abstraction Library (GDAL) is a computer software library for reading and writing raster and vector geospatial data formats (e.g. shapefile), and is released under the permissive X/MIT style free software license by the Open Source Geospatial Foundation.

Each received symbol may be represented in vector form as v r = {r 0, r 1}, where r 0 and r 1 are soft decision values, whose magnitudes signify the joint reliability of the received vector, v r. Every symbol in the code alphabet may, likewise, be represented by the vector v i = {±1, ±1}. The actual computation of the Euclidean distance ...
