geobubble from MATRIX instead of EXCEL

I have this code.

I want to read data from a matrix instead of file AAAA.xlsx.

MATRIX A = [1233 ASDAS 3141

12455 SDR 5544

etc....]

function UserDispersionButtonPushed(app, event)
            tsunamis = readtable('AAAA.xlsx');
            colordata = categorical(tsunamis.cause);
            %geobasemap('colorterrain');
            gb = geobubble(app.UserFlowPanel,tsunamis.lat,tsunamis.lon,tsunamis.count,colordata,'Basemap','colorterrain','Title','User Flow');%   gb = geobubble(app.UserFlowPanel,tsunamis.lat,tsunamis.lon,tsunamis.count,colordata,'Title','User Flow')
      
            gb.SizeLegendTitle = 'Count';
            gb.ColorLegendTitle = 'cause';
            %geobasemap('colorterrain');
        end

How can I do ?
