how to check time in if statement?

In if statement i want to check the timing of the signal . I mean for zero second output is 5 else 2 . And this repeats for few other conditions of time.

like,

If t=0
res=5;
elseif t=6
res=7;
else
res=0;

(all times in seconds)

See examples of correct usage of if statements testing for equality

can I use vector in if to check condition?

Time is in vector and I want to check the test at particular time.

Read about tic toc.

I want to generate pulse train at different times.Not just integers.

if time=0 %ns

result =0;

elseif time =20 %ns

result=3;% rising edge(in volt)

elseif time=35 %in ns

result= 0;% falling edge

elseif time =45 %in nano sec

result =4 % in volt

else

result=0;

I am getting error if i use time in if statement.

Show us the complete code and the error.

[Adam Danz]

The error is here

If t=0

and the OP should be able to figure this one out by looking at examples in the documentation.

I am using step block from simulink ,to get 5 amplitude i multiplied it with 5 from matlab function

code is written in matlab and step block is from simulink

Consider,

i want

0 to 100ns output zero ,

100 to 300 o/p 5 volt

300 to 500 o/p 0

500to 700 o/p 5

700 to 900 o/p 0

and till simulation time o/p zero.
