The smallest of these is 490/70=7, which will set x3 to 0, so our new active variables are x1 and x3. Now let us see how all of this can be done in terms of matrix manipulation. We begin with a matrix A whose rows correspond to the labor, fabric and padding equations. We will add an additional row at the bottom to correspond to the profit equation:

Debugging hints: whos will get you a list of the matrices in use. You should use whos after you have run the program at least once. The list tells the size of each matrix. If you type the name of the matrix, Matlab will print the values of the matrix on the screen. This command is very handy for debugging.

The default type for any variable or quantity in MATLAB is a matrix---a two-dimensional array. Scalars and vectors are regarded as special cases of matrices. A scalar is a 1 by 1matrix, while a vector is an n by 1 or 1 by n matrix. A matrix is entered by rows, with entries in a row separated by spaces or commas, and the rows separated by ...

Use solve to obtain more precise values and check the equation for those values. Symbolic and Numerical Integration. We have not yet dealt with integration. MATLAB has a symbolic integrator, called int, that will easily integrate f. intsf=int(f,0,2) However, if we replace f by the function h, defined by. h=sqrt(x^2-sin(x^4))
