[sim, out] = ld_ReadAsciiFile(sim, events, fname, veclen)
Read data from an ascii-file
fname - file name (string)
veclen - Size of the vector to read during each time-step
out *(veclen) - Output signal as read from the file
The data contained in the file must be ascii data divided into rows and columns
as it may be read on Scilab using the command "fscanfMat".
The number of columns must be veclen.
For each time-step the respectively next row of data is read from the file and
copied to the block's output vectorial signal "out"
The file must be available only at runtime.
