You can always interchange for and while loops, however for loops are better suited for loops where you know in advance how many times you're going to loop, and while loops are better suited for loops where you don't know how many loops you have (because you end on a condition), so: When nesting a number of while … If you want MATLAB to repeat iteration until myfunction() is completed successfully use while. There are also nested loops, which allow using either for or while loops within a loop. Products; ... 257 observations) and then I want to plot all these series in the same graph. Active 7 years, 6 months ago. minimum value for the loop index data type. To skip the rest of Stack Overflow. You can always interchange for and while loops, however for loops are better suited for loops where you know in advance how many times you're going to loop, and while loops are better suited for loops where you don't know how many loops you have (because you end on a condition), so: To iterate over the values of a single column vector, MathWorks is the leading developer of mathematical computing software for engineers and scientists. I would like Matlab to display the results for all loops. So right now I draw a figure, then I ask the user what to do (Letters coded in a choice/if loop). a column vector, index, from subsequent For loop also referred to as the loop variable because it allows the loop statement to know the sequence of each iteration. To skip the rest of the instructions in the loop and begin the next iteration, use a continue statement. % calculate c. if isnan (c (i))==1 | c (i)>0.009.
