MATLAB: Plotting a cellArray Issue

cellarrayplot

Hello,

I have a cellarray thats for example: cellArray = {1X8}; and each cell is 1X1023. But im having issues plotting this. Ive tried cell2mat. But this just returns a giant char array:

c = '205020502049205020512051205120…………'

I tried seperating every 4 chars and plotting but failed. Im trying to read values from a arduino serial port from one of its analog inputs. Ive tried cellfun(@plot,cellArray); and plot(cellArray{1,1}); but get invalid first argument errors…..at a bit of a loss, and I know its a simple solution just stuck.

Hi m j,

Can you try something like this?

celldata(j) = str2num(x)

By doing this you are just storing them as numbers but not as str cell. and you can easily plot.

a1=find(A==2)-1; %find the index of the 2
a2=find(A==3)-1; %find the index of the 3
a2=repmat(a2,2,1) %duplicate the 3 indexes
B=sort([a1;a2])'; %join and sort the solution, also transpose
%I transposed B because of your B example

MATLAB: How I convert a str to Num, and label them. please help me.

Perhaps you are looking for something like this:

function num_arr = convert_to_num420(str_cell_arr)
num_arr = zeros(size(str_cell_arr))-1;
num_arr(strcmp(str_cell_arr,'normal.')) = 1;
X = {'back.','land.','neptune.','pod.','smurf.','teardrop.'};
for k = 1:numel(X)
    num_arr(strcmp(str_cell_arr,X{k})) = 2;
end
end

And tested:

>> convert_to_num420({'normal.'})
ans =  1
>> convert_to_num420({'back.','normal.','smurf.','false!'})
ans =  2   1   2  -1
