Im making a chess game in c plus plus using names for pieces how do you create a string matrix for the board?
One way to represent the state of a Chess board as a string matrix containing names of pieces, is to have an array of pointers. Each pointer would either point to a piece name, or it would be NULL, indicating no piece is there...
char *board[8][8];
int i, j;
for (i=0; i<8; i++) for (j=0; j<8; j++) board[i][j] = NULL; // clear board
board[0][0] = "White Rook";
board[0][1] = "White Bishop";
board[1][0] = "White Pawn"; // etc...

String to matrix converting matlab code?
Here is an example code snippet in MATLAB that converts a string into a matrix: str = '123456789'; % input string numChars = length(str); % number of characters in the string matrixSize = ceil(sqrt(numChars)); % calculate the size of the resulting matrix % pad the string with zeros to make it divisible by the matrix size str = [str, num2str(zeros(1, matrixSize^2 - numChars))]; % reshape the string into a matrix matrix = reshape(str, matrixSize, matrixSize); This code takes an input string and calculates the size of the matrix needed to store all the characters. It then pads the string with zeros to make it divisible by the matrix size. Finally, it uses the reshape function to convert the string into a matrix.
