Problem with fixed point tools

hi every one,

i am simulating a model using blocks from both simscape and commonly used blocks. I got results in earlier version of matlab, but when i simulate it in new version it is giving the following error.

"Values of BreakpointsForDimension1 in 'm_1/pulse generator/Repeating Sequence1/Look-Up Table1' must be monotonically increasing. The problem occurs at the number 3 breakpoint. Please change the breakpoint data or use the fixedpoint tools such as Auto Scaling or Fixed-Point Advisor to determine a different parameter dialog type"

plese help me in overcoming this problem,

thank you.

1. Repeating Sequence block is a masked subsystem block having the Lookup 1-d block underneath it in MATLAB R2013b and before. In current releases, the 1-d block is replaced by the new n-D Lookup table block. The n-D lookup table block only accepts strictly monotonic values.

2. A workaround to this issue can be to change it to [0 0.00002 0.00002+eps]. 'eps' is the smallest floating-point number that can be recognized by MATLAB. Its value is 2^(-52). If you change the value to [0 0.00002 0.00002+eps] in repeating sequence generator. can find that the error is not occurring

Dear Sir .

I have small confision :

where i need to change the value in in time parameter in repeated block as i have below parameters value in repeated block :

time value =[0 11 11 15 15 23 23 28 28 49 49 61 61 85 85 96 96 117 117 143 143 155 155 163 163 176 176 188 188 195]

output value =[0 0 11.1 11.1 2 2 -2.8 -2.8 0 0 18.2 18.2 5.1 5.1 -5.6 -5.6 0 0 23.2 23.2 10.5 10.5 -8.5 -8.5 5.8 5.8 -6.2 -6.2 0 0]
