# csvTextScan

Convert a comma-separated value to a matrix

### Syntax

A = csvTextScan(M) A = csvTextScan(M, separator) A = csvTextScan(M, separator, decimal) A = csvTextScan(M, separator, decimal, conversion) A = csvTextScan(M, separator, decimal, conversion, range)

### Parameters

- M
a m-by-1 or 1-by-m matrix of strings.

- separator
a 1-by-1 matrix of strings, the column separator mark.

- decimal
a 1-by-1 matrix of strings, the decimal mark. The available values are "." or ",".

If

`decimal`

is different of`[]`

and`conversion`

is set to`string`

, the decimal conversion will be done.- conversion
a 1-by-1 matrix of strings, the type of the output

`A`

. Available values are "string" or "double".- range
a 1-by-4 or 4-by-1 matrix of floating point integers, the range of rows and columns which must be read (default range=[], meaning that all the rows and columns). Specify range using the format

`[R1 C1 R2 C2]`

where (R1,C1) is the upper left corner of the data to be read and (R2,C2) is the lower right corner.- A
a m-by-n matrix of strings or double.

### Description

Given an ascii file with delimited fields, this function returns the corresponding Scilab matrix of strings or doubles.

The `csvTextScan`

function has the same purpose as
`csvRead`

, except that `csvTextScan`

reads in a string, while `csvRead`

reads in a
file.

The default value of the optional input arguments are defined by the
`csvDefault`

function.

Any optional input argument equal to the empty matrix
`[]`

is set to its default value.

When input argument "conversion" is equal to "double", strings are converted as NaN.

### Examples

// convert a csv string matrix to splitted string or double matrix A = ["1;3 + i"; "Nan;-Inf"] B = csvTextScan(A,';') C = csvTextScan(A,';',[],'double') // // Configure the decimal mark. Atext = [ " 1,000000000D+00; 0,000000000D+00; 2,000000000D+02; Inf; 0,000000000D+00"; " 1,000000000D+00; 1,00000000D-300; 2,000000000D+02; Inf; 0,000000000D+00"; " 1,000000000D+00; 1,00000000D-200; 2,000000000D+02; 3,15000000D+300; 1,020000000D+02"; " 9,999999999D-01; 1,00000000D-100; 2,000000000D+02; 2,960000000D+02; 1,170000000D+02"; " 1,000000000D+00; Inf;-Inf; Nan; 0,000000000D+00" ]; csvTextScan( Atext , ";" , "," )
