dlmread (MATLAB Function Reference)

Read an ASCII delimited file into a matrix

Syntax

M = dlmread(filename,delimiter)
M = dlmread(filename,delimiter,r,c)
M = dlmread(filename,delimiter,range)

Description

M = dlmread(filename,delimiter)

reads data from the ASCII delimited format filename, using the delimiter delimiter. A comma (,) is the default delimiter. Use '\t' to specify a tab delimiter.

M = dlmread(filename,delimiter,r,c)

reads data from the ASCII delimited format filename, using the delimiter delimiter, starting at file offset r and c, where r is the row offset and c is the column offset. r and c are zero based so that r=0, c=0 specifies the first value in the file, which is the upper left corner. A comma (,) is the default delimiter. Use '\t' to specify a tab delimiter.

M = dlmread(filename,delimiter,range)

imports an indexed or named range of ASCII-delimited data, using the delimiter delimiter. A comma (,) is the default delimiter. Use '\t' to specify a tab delimiter. Specify range by

range = [UpperLeftRow UpperLeftColumn LowerRightRow 
LowerRightColumn]

or using spreadsheet notation, for example,

range = 'a1..b7'

Remarks

dlmread fills empty delimited fields with zero. Data files having lines that end with a non-space delimiter produce a result that has an additional last column of zeros.
