You can customize aspects of the import using name-value arguments or an import options object.

I might just resort to the old "one at a time" here with fgetl and split , though, and be done with it. Flag to preserve variable names, specified as either "modify" or "preserve". This is unexpected, especially considering that writetable writes logical values as '0' and '1'. Specify RowNamesRange as one of the values in this table. You must also specify the Delimiter option. The VariableWidths property contains an entry corresponding to each variable specified in the VariableNames property. Example: "A5" or 5 " Corner1:Corner2 " Rectangular Range Specify the exact range to read using the rectangular range form, where Corner1 and Corner2 are two opposing corners that define the region to read.

ImportErrorRule — Procedure to handle import errors "fill" default "error" "omitrow" "omitvar".

You can read a CSV file using the readtable function. This function reads the file data and saves it in a table that contains variables on each column. If the CSV file does not contain variables on each column, the readtable function will give them a default variable name starting from var1 and so on.

For instance, you can select a rectangular portion of the spreadsheet and call it "myTable". For example, specify the first row as a header line to skip before reading data. Ra: Results of detectImportOptions function used by default to import tabular data By default, the readtable function uses the results of the detectImportOptions function to import tabular data. If you specify the Sheet argument in addition to opts the import options, then the readtable function uses the specified value for Sheet argument, overriding the sheet name defined in the import options. Playing around with fgetl and split seems to get me quite far! Data is considered missing if an expected field in a row does not exist. DecimalSeparator — Characters indicating decimal separator character vector string scalar. Before Ra, use commas to separate each name and value, and enclose Name in quotes. Read Text File with Missing Data. The problem is that readtable does not read the file as having rows, but only 4, due to the rows without data.
