READC_f

Read binary data

Block Screenshot

Description

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.

Dialog box

  • 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. ,The th element of the read record gives the value of 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
