How to form a for loop which performs descending order in Scilab -

i trying perform descend loop in scilab like:

for i=7: 1      disp(i); end 

but apparently didn't work , there no errors too.

is possible? , if yes, how it?

syntax

as for-loop documentation states, loop's syntax is:

for variable=expression instruction, ,instruction,end 

if expression matrix or row vector, variable takes values values of each column of matrix.

your example

your for-loop uses 7:1 expression, result in valid empty vector:

-->7:1  ans  =       [] 

the for-loop takes each value in vector , finishes, since vector empty finishes directly. valid syntax.

working example

the documentation gives following example of working decreasing loop:

for j=4:-1:1    disp(j); end // decreasing loop
