MATLAB decoding ''braille'' using a table file to decode input into english. Issue with string being returned as a double + possible incorrect use of iterations in for loop?
for instance an input of a matrix = [1 0 0; 0 0 0] (which is equivalent to the first six elements in the table file) will return a double = [97, 0] also, I'm not sure where the zero is coming from I'm lost and would appreciate any hints. Thank you :)
function output = b_decode(input);
load('braille_table.mat', 'table');
x = numel(input)
[r,c] = size(input)
str = zeros(1,c)
for i = 1:6:c;
j = 1:1:(c./2);
if input(i:i+5) == table(1:6)
str(j) = 'a'
elseif input(i:i+5) == table(7:12)
str(j) = 'b'
