Manipulating Data in cell array, especially Inf

Hey there,

i have a 25x25 cell arrays which includes mostly numbers or doubles to be precise. Now some values are Infinity, displayed by the Inf keyword. Now i want to copy the cell array in to an 2d array and exchange the Inf's with ones. But i cant seem to figure it out. Maybe you guys know more ? With L_d_0 being the 2d cell array containing the data i want to copy / exchange with ones if they are Inf.

L_d_Matrix=zeros(25,25);

for i=1:length(L_d_0)

for j=1:length(L_d_0)

L_d_Matrix(i,j)=L_d_0{i,j};

if L_d_Matrix(i,j) == inf

L_d_Matrix(i,j) = 1;

end

end

end

Haha! I shouldve checked my spelling, its because inf is supposed to bei Inf. Yikes ! NVM guys. :)

isequal(inf,Inf)

ans = logical
   1

PS: use ISINF rather than EQ.

I think that you can try this method on the other hand, that method shorter than if else method.

%Example Matrix
L_d_Matrix=[inf,5,2;inf,inf,inf;1,2,3]

L_d_Matrix = 3×3

Inf 5 2 Inf Inf Inf 1 2 3

%Here we change inf by one
L_d_Matrix(L_d_Matrix==inf)=1

L_d_Matrix = 3×3

1 5 2 1 1 1 1 2 3
