[PrString, ErrMsg] = prprintf(Format, Between, VarData)
Pretty Print formated of variable This function takes the given variable and produces a string containing the contents of the variable in a pretty printed format. The function checks the variable, if it contains characters. When characters are in the variable/matrix, each row is printed as one string without looking at 'Format'. 'Between' is used as divider. Otherwise (VarData contains only numbers), each element is printed using 'Format'. 'Between' is used to divide the elements of one row. Between rows a number of spaces is included to visually divide the rows. If the variable contains structures or cell arrays, this function is called recursively for every element, even structure arrays. An internal function prstruct handles the special case of structures appropriately. The field names are printed as well, every element on a single line. All this produces a good looking string of the elements in 'VarData' without worrying to much about the format of the elements. Syntax: [PrString, ErrMsg] = prprintf(Format, Between, VarData) Input parameter: Format - (optional) String containing formatstring, uses same syntax as sprintf if omitted, '%g' is used Between - (optional) String containing characters to put between elements in VarData if omitted, ' ' is used VarData - Variable(s) to pretty print, may be a scalar, a character, a string, a matrix, a cell array or a structure with all of this, even mixed up If only 2 input parameters are provided, the first input is Format and the second input VarData, Between is set to an empty string. If only 1 input parameters is provided, the first input is VarData, Format and Between are set to default values. Output parameter: PrString - String containing the elements in VarData pretty printed ErrMsg - String containing possible error message, then PrString is an empty string ErrMsg is an empty matrix, when no error occured Examples: >>prprintf('%g', '/', [1.02 4.07 3.0532]) 1.02/4.07/3.0532 >>prprintf('%.3g ', [1.02 4.07; 3.0532 5.875; 3.324 4.123]) 1.02 4.07 3.05 5.88 3.32 4.12 >>prprintf('%s', ' ', ['eins';'zwei';'drei';'vier']) eins zwei drei vier Try prprintf with cell arrays and structures as well!
