Replace char with other and count total numbers

where x is the object you represent graphically? If you could concatenate all of the vectors in "column" 2 into a single vector, say y, then the number of ones would be O=sum(y) and the number of zeros Z = length(y)-O.

1. this example might help you with your whitespace problem

str = 'hello\nworld';
formattedStr = sprintf(str)
newlineChar = sprintf('\n');
strrep(formattedStr,newlineChar,' ')

2. you can get number of zeros and ones by the following:

if your variable is x, then

number_of_ones  = sum([x{:,2}]);
number_of_zeros = length([x{:,2}]) - number_of_ones;

It appears that you are working with cell arrays. Make sure you use the curly braces and square brackets (not parens) when executing this code (e.g. [x{:,2}]). If this still doesn't work, post how you construct your data array.

What do you exactly mean by "this variable which is depicted above" and where would the \n be?

I think tdd4c1 answered to your question about the newline above. Doesn't it work?

As to converting a string to char, I think it's enough to enclose it in braces

cell_a = {a}

sorry, I forgot to insert the image. No it didn't work what tdd4c1 suggested me.

oh, ok... maybe attaching the mat file containing the char variable instead of its graphical representation would be more helpful in pinpointing the problem.

Even better would be a small portion of the variable that sufficient to exemplify the problem (a minimal example, that is).
