excel sum all cells where another cell contains a string -



excel sum all cells where another cell contains a string -

example table:

| | b -------------------------- 1 | 26 | tom, jerry -------------------------- 2 | 12 | tom -------------------------- 3 | 6 | jerry, tom, dick

suppose have table. trying sum total of cells in column cell of same row in column b contains name, illustration "tom". however, before cell in column added total, has divided number of names in column b.

so example, if used name jerry, total of:

(26/2) + (6/3) = 15

if used name tom, total of:

(26/2) + 12 + (6/3) = 27

please help! thinking perhaps might complex , might need split up.

assuming name in cell c1, formula job:

=sum($a$1:$a$3*not(iserror(search(c1,$b$1:$b$3)))/(len($b$1:$b$3)-len(substitute($b$1:$b$3,",",""))+1))

you need come in array formula, i.e. press ctrl-shift-enter.

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
