Scicos Block READC_f - Scicos "read from C binary file" block
Description
This block allows user to read datas 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.
DIALOGUE PARAMETERS
- Time record Selection
: an empty matrix or a positive integer. If an integer i is given the ith element of the read record is assumed to be the date of the output event. If empty no output event exists.
- Output record selection
: a vector of positive integer. [k1,..,kn],The kith element of the read record gives the value of ith output.
- Input file name
: a character string defining the path of the file
- Input Format
: a character string defining the format to use
- "l","s","ul","us","d","f","c","uc"
: for reading respectively long, ashort, unsigned long, unsigned short, double, float, char and unsigned char. If required by the swap mode, the bytes which are read are automatically swapped if necessary (by checking little-endian status) in order to produce machine independent binary files ( in little-endian mode).
- "ull","uls","ubl","ubs",
: can be used for reading respectively unsigned little-endian long or short and unsigned big-endian long or short.
- "dx","fx","lx","sx"
: with x=b or x=l can be used for reading double, float, long or short as big or little endian.
- 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.
- 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.
- Initial record index
: a scalar. This fixes the first record of the file to use.
- Swap mode
: 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.
