Read binary data

This block allows user to read data in a C file. Output record selection and Time record Selection allows the user to select data among file records. Each call to the block advance one record in the file.

Time record selection
an empty matrix or a positive integer.
If an integer i is given the i th element of the read record is assumed to be the date of the output event.
If empty no output event exists.
Properties : Type 'vec' of size -1
Outputs record selection
a vector of positive integer.
$[k_1,\cdots,k_n]$ ,The th element of the read record gives the value of $i^{th}$ output.
Properties : Type 'vec' of size -1
Input file name
a character string defining the path of the file.
Properties : Type 'str' of size 1
Input Format
a character string defining the format to use.
Properties : Type 'str' of size 1
Record size
The file is supposed to be formed by a sequence of data with same format.
These data are organized in a sequence of record each of them containing Record size data.
Properties : Type 'vec' of size 1
Buffer size
To improve efficiency it is possible to buffer the input data. Read on the file is only done after each Buffer size call to the block.
Properties : Type 'vec' of size 1
Initial record index
a scalar. This fixes the first record of the file to use.
Properties : Type 'vec' of size 1
Swap mode 0/1
With Swap mode=1 the file is supposed to be coded in "little endian IEEE format" and data are swaped if necessary to match the IEEE format of the processor. If Swap mode=0 then automatic bytes swap is disabled.
Properties : Type 'vec' of size 1
