Using num2str to get brackets

Hi,

from

A = [ 54,0.04;  60,0.03;  65,0.02;  67,0.01];

I want to get:

B = [(54,0.04);(60,0.03);(65,0.02),(67,0.01)];

Which I will use to display in a plot. The problem is I can get the comma in the middle using num2str but not the brackets on either side.

I have tried:

for j = 1:size(A,1)
    B(j) = ['[',num2str(A(:,1),'%5.3g),']'];
end

But I get a dimension error. Not sure what to try next.

Any help will be great. Thanks

Another alternative using sprintf and mat2cell:

mat2cell(sprintf('(%2d,%3.2f)',A.'),1, repmat(9,1,numel(A)/2)).'

hi Oleg! more variant

reshape(sprintf('(%2d,%3.2f)',A.'),[],size(A,1))'

I think I just figured it out, by usingthe code beolw in the plot:-

text(A(j,1),A(j,2),['(' num2str(A(j,1)),',' num2str(A(j,2)) ')']
