Hello,

I have created a 13 x 2 cell array that has time values in the first column and keywords in the second column. It takes the form below.

'28979.015' 'hold'

'39780.015' 'hold-end'

'39910.015' 'hold'

'49108.015' 'max-pressure-evac 60.0'

'50711.015' 'hold-end'

'50841.015' 'hold'

'58642.015' 'hold-end'

'58772.015' 'hold'

'65837.015' 'max-pressure-evac 60.0'

'65973.015' 'hold-end'

'66103.015' 'hold'

'72410.015' 'max-pressure-evac 60.0'

'73304.015' 'hold-end'

I would like to add a row underneath every 'max-pressure-evac 60.0' where in the first column a constant of 61 is added to the previous value and the second column takes on the name 'evac-end'. For example:

'49108.015' 'max-pressure-evac 60.0'

should become:

'49108.015' 'max-pressure-evac 60.0'

'49169.015' 'evac-end'

Any advice on how this can be accomplished would be greatly appreciated. Thank you in advance.

在 MATLAB Online 中打开

a=strcmp(yourCell(:,2),'max-pressure-evac 60.0');
f=find(a)';
f=f+(0:numel(f)-1);
for k=f
  yourCell(k+1:end+1,:)=yourCell(k:end,:);
  yourCell{k+1,1}=num2str(str2double(yourCell{k+1,1})+60);
  yourCell{k+1,2}='evac-end';
end
