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);
