Dynamic array for string

D = 0.067;

Ugs = [0.047,0.061,0.288,0.344,0.404,0.544,0.709,0.945,1.418,1.891,2.363,2.836,4.727];

Uls = ones(1,13)*0.047;

L = 6.0000;

g = 9.81;

% Um=zeros(Ugs.size);

Um = Ugs + Uls;

Le = 42.6 * D *((Um/((g*D)^0.5))+0.29);

for i = 1:13

if L < Le:13

flow='churn'

else

if L >= Le:13

flow='slug'

arrow(i,:) = flow;

end

end

end

Ugs = Ugs.';

Le = Le.';

Um = Um.';

flow = flow.';

Uls = Uls.';

P = plot(Le,Um)

T = table(Uls,Ugs,Le,Um,arrow)

Answer 1

[Mehmed Saad]

cells are used for that purpose

arrow{i} = flow;%  braces changed

Take transpose of arrow like you are doing for other variables

also this line will give you error.

if L >= Le:13

for indexing replace Le:13 with Le(i)

the final table you will get is

T =

13×5 table

Uls Ugs Le Um arrow
