Intelligent Numerical Computation2 Basic structure of a flowchart or a program start end statements Statements are executed one by one A statement can be an assignment: A = B*C-D : x = sort(x) a function for I/O : plot(x,y) : imread(X) a control statement -- if statement -- if else statement -- for statement -- while statement

Intelligent Numerical Computation3 Control statements If statement condition statements false true tag = 0; if ~ tag tag = tag+1; end

Intelligent Numerical Computation4 Control statements If else statement condition statements false or 0 true or 1 statements if ~ tag tag = tag +1; else tag = tag –1; end

Intelligent Numerical Computation5 Control statements for statement statements false true Example x=2; for i = 1:10 x = x*x; end i =1 i=i+1
