char converts in a character array y = char(x) y = char(st1, st2, st3,...) x a cell array of strings, or an array of ASCII codes. st1, st2, st3 arrays of strings. y a vector of strings (column). One input argument : Given a cell of array of strings x, this function returns a vector of strings y in which the rows are the concatenated components of corresponding rows of the cell array of strings. Given an array of ASCII codes x, this function returns a array of strings y corresponding into ASCII codes. If dimensions of x are [n1, n2, n3, n4,...], then returned value has same size as input value except second dimension, i.e. the dimensions of y are [n1, n3, n4,...]. More than one input argument : Given arrays of strings st1, st2, st3,..., this function returns a vector of strings in which the rows are the concatenated components of corresponding rows of st1, st2, st3,.... In the vector y all strings sti are completed by blanks to have the same length as the max length of sti. ascii asciimat
