Data type error using 'find'

I have a list of double values(Test.TempCcol_10) in which one I want to find the indexes where the doubles values match with cond1(cell type since is taken from a listbox).

list1 = find(cell2mat(Test.TempCcol_10) == cond1)

If I introduced the cond1 as a double the command works perfectly but when cond1 is taken from a listbox I got the next error:

Undefined function 'eq' for input arguments of type 'cell'.

Error in plot_project(line 29)
list1 = find(cell2mat(Test.TempCcol_10) == cond1);

I tried to convert the cond1 but without succes.

Thanks in advance.

Try this

list1 = find(cell2mat(Test.TempCcol_10) == str2double(cond1));
