MATLAB: Round values in cell array to n(10)

cell arrayround

How to round the following…

cell = {15;26;37;48;50;68};
cell2 = roundn(cell,1)

cell2 = {20;30;40;50;50;70};

How would it change if I wanted to round just up or down and not to the nearest n(10)?

Best Answer

c = {15;26;37;48;50;68};
N = -1; % Digit to round to. N=-1 will round to tens. N=0 will round to nearest integer
c2 = cellfun(@(x)round(x,N),c)

Side note: It is a bad idea to name a variable with a MATLAB keyword such as "cell".

Gamosa Neki?

Please note you can assign the rows number at the begining of the array. I way to store the all indexing (rows,colm) of non white pixels.

im_test=imread('PAIKOK.png');
[idx1,idx2]=find(im_test==1);

Here idx1 and idx2 store the all color pixel location of the indexed image. Afterwards you can retrive the image by having same size and assign the same color on those idx1 and idx2 position.

Here I have use the for loop just try to display as per your requiremnets. Same the individual column locations in cell array and retrive when it required.

Is this?

im_test=imread('PAIKOK.png');
[rows colm]=size(im_test);
for i=1:rows
[i,idx2]=find(im_test(i,:)==1);
disp(idx2);
end

Hope it gives you sufficient hints!
