Matt gave a good explanation. I'd just like to add a few things. With a cell array, you refer to a cell with a number (the index), with a structure you refer to a "member" with its name. For example ca{1} = 'Hello manoj' while myStruct.myString = 'Hello manoj'. You see, the number 1 for the cell index, and "myString" for the structure member (or "field") name.

A cell in a cell array is referred to with parentheses, while the contents of the cell are referred to with braces. For example ca(1) would be a cell and that cell might have a string in it, while ca{1} would be the contents of ca(1) which would be the actual string itself, say, 'Hello manoj'.

There is also a function called celldisp() to display the cell contents.

thanks very much

Answer 2

There is good documentation on this, did you read:

doc cell
doc struct

Here is a cell array:

C{1} = magic(3);
C{2} = 'A character array!';
C{3} = 3

Here is a structure:

S.color = 'red';
S.length = 5;
S.matrix = eye(4)

Now look at how you get information out of both of these:

C{2}  % Displays the contents of cell 2 of cell array C
S.matrix  % Shows contents of field 'matrix' of struct S.

The following equation describes the motion of a certain mass connected to a spring, with viscous friction on the surface

3j + 39j + 120y = f(t)

where f(t) is an applied force. Suppose that f(t) = 0 for t < 0 and f(t) = 10 t >= 0

a. Plot y(t) for y(0)= dot y(0) = 0 .

b. Plot y(t) for y(0) = 0 and iv(0) = 10 Discuss the effect of the nonzero initial velocity.

Use the ode 45 Solver for this problem.
