Hey
I have a cell array (1000x2 cell) with colom a = dates(strings) and b=hours (numbers). Now I would like to find a the row with a certain date and hour=12. So far I made this
K>> start=find(strncmpi(A(1),[time{:,1}],8))&find([time{:,2}] == 12); Error using & Inputs must have the same size.
K>> start=find(strncmpi(A(1),[time{:,1}],8))&&find([time{:,2}] == 12); Operands to the and && operators must be convertible to logical scalar values.
Which character do I need to use to make this work??
Thanks! Tessa

Hi,
I guess your cell array (1000x2 cell) is time.
Not knowing hat are all your data (A,time), I can just guess :
time = {...
'01022014' , 8;...
'05072014' , 12;...
'12062014' , 3};
a = time(:,1);
b = cell2mat(time(:,2));
A = '05072014';
H = 12;
start = find(strncmpi(A,a,8) & b==H);
