excel - Sum cells if date is correct (SUMIF) -

-

i having little problem google spreadsheets. spreadsheet looks this:

a                       b              c 24.11.2014 07:30:12  fruit            500    24.11.2014 17:34:32  meat             450  25.11.2014 07:30:09  blah            1000 25.11.2014 18:30:47  blah             802

now want add numbers in c:c if date equals 24.11.2014. first guess using:

=sumif(a:a,">="&e2,c:c)

where e2 = 24.11.2014

after messing around it, still gives me parsing error. sumif works google spreadsheets.

thanks help!

here simplest solution: 

=sumif(a:a;"*"&e2&"*";c:c)



enter image description here

you sum values in c:c if find e2 in a:a. , result 950 in example. hope works fine.

i'm trying plot frequency characteristic equation using ezplot, matlab gives following warning, "contour not rendered non-finite zdata". have used command plot frequency equations warning , plot display empty , not change axis range well. can please help. appreciated. here's code i'm using. % transfer matrix case-i, thin rotor clear all; clc; ei = 1626; l = 0.15; m = 0.44108; = 2.178*10^-4; i_p = 2.205*10^-5; itr = 0.24; i_pr = 0.479; syms p n; f = [1 l*1i l^2/(2*ei)*1i l^3/(6*ei); 0 1 l/ei -l^2/(2*ei)*1i; 0 0 1 -l*1i; 0 0 0 l]; p = [ 1 0 0 0; 0 1 0 0; 0 -it*p^2+i_p*n*p 1 0; -m*p^2 0 0 1]; p_r = [1 0 0 0; 0 1 0 0; 0 -itr*p^2+i_pr*n*p 1 0; -m*p^2 0 0 1]; = f*p*f*p*f*p*f; b = p_r*f*p*f*p*f; r = a(1,2)/a(1,4); a12_p = 0; a22_p = a(2,2)-r*a(2,4); a32_p = a(3,2)-r*a(3,4); a42_p = a(4,2)-r*a(4,4); ap(2,2) = a22_p; ap(3,2) = a32_p; ap(4,2) = a42_p; ap(4,4) = 1; c = b*ap; m = [c(3,2) c(3,4); c(4,2) c(4,...
