matlab

Write a script (only a very few lines) to determine the maximum value and its index of the vector x, and to print out maximum value = ..., index = ... using disp, where "..." must be filled in, and the sentence must end with a period. Assume that the matrix F has already been entered into MATLAB, but you don't yet know its size. Write the MATLAB code needed to answer each part using disp. Print out The matrix F has ... rows and ... columns. where it is your responsibility to fill in "...". Print out The maximum value of F is ... where you must include the dot at the end of this sentence. Print out The sum of the diagonal elements of F is .... where you must include the dot at the end of this sentence.

Explanation / Answer

[a]

A = [1 5 4 ;6 8 9 ;2 1 3];

[v,ind]=max(A);

[v1,ind1]=max(max(A));

disp(sprintf('Maximum value = %d , index = (%d,%d).', v1, ind(ind1), ind1 ));

[b]

F = [1 5 4 ;6 8 9 ;2 1 3];

[row , col] = size(F);

X = sprintf('The matrix F has %d rows and %d columns.',row,col);

disp (X)

[v,ind]=max(F);

[v1,ind1]=max(max(F));

Y = sprintf('The maximum value of F is %d .',v1);

disp (Y)

total = sum(diag(F));

Z = sprintf('The Sum of the diagonal Element is = %d .',total);

disp (Z)
