I have a table that includes my full csv (with headers) and I am hoping to search for a specific header name (cellSize) and pull that data into a structure I can multiply.

If you loaded the .csv into a table with headers that are variable names, you don't need to search nor "pull" data -- just reference it directly.

newvar=t.cellSize*pi;       % multiply cellSize table "t" variable by pi; store in array
t.newvar=t.cellSize*pi;     % multiply cellSize table "t" variable by pi; store in new var in table "t"
