Robust Data File Reading utility Matlab script

Publisher review:
Robust Data File Reading utility imports data from a comma- or tab-delimitted file. RDFREAD handles comma-delimitted and tab-delimitted files and expects, but does not require the variable (column) names to be in the first line. Data may have missing values and character values mixed in the numeric data columns. All non-numerics in data lines are changed to NaN. This function does not properly read character variable columns, but instead turns such data into an entire column of missing values.If the firstline has no numerics, it is assumed to be a header line with variable names. In this case a structure class is created with the fields name.varnames & name.data. If there is no headerline, a simple data matrix is created.If there is no output argument (nargout=0), the results are put into base memory using filename as name.examples RDFREAD -- no input args, uses GUI file selection (uigetfiles)RDFREAD(1) -- command line versionRDFREAD('file_name','C:data_path') -- works (path is optional)xdat= RDFREAD('file_name') -- results placed in xdat Below is an example of a messy data file that this utilty fucntion can read.SECID,DATE,PRC,X110001,19970131,8.625,110002,1997215,13,10003,,-15,41099a,o.0,.T,NaNxd,,.,1.111999,2,3,6In this case, the RDFREAD 'data' results are 10001 19970131 8.625 110002 1997215 13 NaN10003 NaN -15 4NaN NaN NaN NaNNaN NaN NaN 1.111999 2 3 6and filename.varnames= 'SECID' 'DATE' 'PRC' 'X1'Note that this function is considerably slower than i/o routines such as LOAD and DLMREAD because it reads and parses one line at a time, but it works in a much more robust manner as long as you do not need to read in 'character' columns.
