Basics of MATLAB and Beyond

Weused the curly brackets t{1,2} to refer to that particular cell. If we hadused ordinary round brackets, we would have produced an error:>> t(1,2) = spiral(3)??? Conversion to cell from double is not possible.This is because there is a difference between indexing cells and indexingtheir contents. For example, to extract the word “virtue” from the secondline of the quotation in the first column, we need to access the cell {2,1},then get characters 15 to 20 from that cell’s contents:>> t{2,1}(15:20)ans =virtueWhen assigning a cell you can use the curly brackets on either the left orright hand side of the equals sign, but you must put them somewhere, totell matlab that you want this to be a cell. Otherwise, matlab thinksyou are defining a mathematical matrix and gives you an error to theeffect that the things on each side of the equal sign have different sizes.For example, we can type:c○ 2000 by CRC Press LLC
