i tried generating cone of influence morlet wavelet power spectrum using following matlab code: cone = conofinf('morl',1:365,lensig,[],'plot'); however, strange looking shaded area bounded 2 linear lines. doesn't cone of influence morlet wavelet power spectrum. what did wrong? i guess wanted output coi @ borders of wavelet transform. in case have specify last parameter non-empty vector, coordinates, need coi computed, e.g. cone = conofinf('morl',1:365,lensig,[1 lensig],'plot'); i had similar task , here's did: figure; % plot wavelet transform / scalogram imagesc(t,scales,wt); axis square; colorbar; % annotate axes , title title('coefficients of continuous wavelet transform'); xlabel('time (or space) b'); ylabel('scales a'); % cone of influence % here, have specify points @ want calculate coi % last parameter: cone = conofinf(wname,scales,lensig,[1 lensig]); % combine left , right edges cone = ...

i have code: let posstate = positionstate(pos) if posstate != .none { if posstate == .off { boardarray[pos.row][pos.column] == .on } else { boardarray[pos.row][pos.column] == .off } } the issue i'm having when attempt change value of element in boardarray , nothing happens. why boardarray's element stay same? you using == rather = assigning let posstate = positionstate(pos) if posstate != .none { if posstate == .off { boardarray[pos.row][pos.column] = .on } else { boardarray[pos.row][pos.column] = .off } }
