How to make a loop to the if else situation ?

2 visualizzazioni (ultimi 30 giorni)
I have a coding as follows:
if (idxi >=1) && (idxi <=5)
idx='1';
elseif (idxi >=6) && (idxi <=10)
idx='2';
elseif (idxi >=11) && (idxi <=15)
idx='3';
elseif (idxi >=16) && (idxi <=20)
idx='4';
elseif (idxi >=21) && (idxi <=25)
idx='5';
The following coding explained that I had a 25 images in a folder in the directory C. Here I make a conditional if, if idxi obtained has a range of 1-5, it is shown is data from mysql database that has idx = 1, when the idxi gained have 6-10 range, then that is displayed is the data from mysql database that has the idx = 2 and so on. But if I add as many as five images into the folder, it means I have to go back to add an if statement in the coding .. What I want to ask is, if I could make a loop so that I do not need to add a conditional if again if I add a new image?

idx = num2str( ceil( idxi / 5 ) );
works if you will always have 5 images in each group and continue that same logic.
