2 Structure Variables and Cell Arrays

This section is about combining strings with numbers - which we use for asset names in finance and making sense of output matrices.

2.1

Create some variables with the following code.

vari-('F:AC', 'U: IBM'}; var2-[1:9]:

var3-[1,2,3,4,5,6,7,8,9];

Put each of these variables into a structure variable called mat. Required: mat should have 3 parts to it, with each name based on the corresponding variable.

2.2

Put each of the variables from question (2.1) directly into a cell array called matcell. Required: matcell should have 3 parts to it (make 3 rows and 1 column). Hint: size (matcell) should be 3 1.

2.3

Let rans1 = what would be the result of var2+ reshape(var3, 1, 9). Required: Get the numbers for var2 by directly referencing mal and get those from var3 by directly referencing matcell.

2.4

Create three new variables with the following code.

Townames {; '2002; 2003; 2004'}; colnames-'Nasdaq Stock', 'LSE Stock');

prices-[12,110;11,109:6,105]:
