I'm trying to index data in between two values that vary for each cell.

dew_finalplus=dew_final+1;
dew_finalminus=dew_final-1;
for i=1:length(dew_array)
    dew_final1{i}=mat2cell(dew_finalplus, ones(1, size(dew_finalplus, 1)), size(dew_finalplus, 2));
    dew_final2{i}=mat2cell(dew_finalminus, ones(1, size(dew_finalminus, 1)), size(dew_finalminus, 2));
end

This part was used to convert a matrix dew_final into two seperate matricies with values +1 and -1 from the original matrix. Then I converted it to a cell array to try to combat an error I had before.

for i=1:length(dew_array) 
i;
y_index=find(subdewfinal{i}<=dew_final1{i} & subdewfinal>=dew_final2{i}); 
DewIV=subdewfinal{i}(y_index);

This is the beginning of a for loop I want to find the indicies in subdewfinal in between dewfinal1 and dewfinal2.

I keep gettng an error 'Undefined function 'le' for input arguments of type 'cell'.' I tried using double() but I can't use that for a cell. Any ideas or modifications to help me out? Thanks

There is no "le" in the posted code

在 MATLAB Online 中打开

LE is the less than or equal to operator in the statement

subdewfinal{i}<=dew_final1{i}

These items have still not been resolved into numeric matrices that can be compared with "<=". My guess is that you have cell arrays within cell arrays and that you need to refine your indexing to make sure that you are comparing numeric quantities instead of cells.
