xPC Target™

xpcbytes2file - Generate file suitable for use by From File block

Syntax

xpcbytes2file(filename, var1, ...,varn)

Arguments

Description

The xpcbytes2file function outputs one column of var1,..., varn at every time step. All variables must have the same number of columns; the number of rows and data types can differ.

Note   You might have the data organized such that a row refers to a single time step and not a column. In this case, pass to xpcbytes2file the transpose of the variable. To optimize file writes, organize the data in columns.

Examples

In the following example, to use the From File block to output a variable errorval (single precision, scalar) and velocity (double, width 3) at every time step, you can generate the file with the command:

xpcbytes2file('myfile', errorval, velocity)

where errorval has class 'single' and dimensions [1 x N] and velocity has class 'double' and dimensions [3 x N].

Set up the From File block to output

28 bytes
(1 * sizeof('single') + 3 * sizeof('double'))

at every sample time.
