Hi,
one of the variable is appearing in the following way:
but I want to put '|' sign instead of 45 in the numerical matrix so that it will show only | instead of 45. I wrote the following code but '|' symbol is appearing as 45 in the numerical array.
---------------------------------------------------
seq1_gap_idx = find(tb=='L');
logical_idx = false(1,length(hsp_u{f_ind1}.seq1(:,1))+length(seq1_gap_idx));
logical_idx(seq1_gap_idx) = true;
new_seq1 = nan(size(logical_idx));
new_seq1(~logical_idx) = hsp_u{f_ind1}.seq1(:,1)';
% new_seq1 = char(new_seq1(logical_idx));
% new_seq1=str(new_seq1)
new_seq1(logical_idx) ='|';
---------------------------------------------------
I will appreciate your help. Thanks

Numeric arrays can never contain strings or characters. It takes the ASCII value of that character if you try to replace an element in numerical matrix with a char”. You can use cell arrays to do this. As an example, refer the following code:
new_seq1 = [45 16 20 42]; % let
new_cell = num2cell(new_seq1); % save numerical array in cell format
new_cell {1} = 'I'; % replace
Refer the following document for more details on Cell Arrays:
