MATLAB: Isempty is allways zero

isempty

Hello,

im using isempty:

TP =
     0     0     0
>> isempty(TP)
ans =
  logical
   0
   
>> TP(3) = 1
TP =
     0     0     1
>> isempty(TP)
ans =
  logical
   0

Why is locical answer still zero? What can I do? I need to check multiple arrays for empty or not in if-else blocks.

zero and empty are different

isempty([])
isempty(0)
isempty('')

MATLAB: Loop through excel files and save output to 1 file

You want to add to the data every loop and write it out once at the end. Before loop data = repmat(cell(1,4),length(xl_file_list),1); % Preallocate for speed

Each loop data(file_number) ={p,tp1,tp2,tp3,tp4};

After loop xlswrite(OutFilename, data)

MATLAB: How the computation happening : sum(A~=0,2)

>>A~=0 % creates a logical matrix so when you sum along rows, you get three
ans =
  3×3 logical array
   1   1   1
   1   1   1
   1   1   1
>> sum(ans,2)
ans =
     3
     3
     3
>> sum(A,2) % perhaps you mean't to do this
ans =
     6
    15
    24
