Combinining the values from a image

I have 7 matrix(30x30 in which there are only 3values) ,and i have used tabulate command for finding the percentage so for each matrix i get percentage values such as

50.1%A

31.7%B

18.2%C these 3 for 1st matrix

11.5%A

19.8%B

68.8%C for 2nd matrix and so on

now i want to combine all A's ,B's ,C's if values are sane or +-5,i want to make it as single value instead of many,i want to reduce the number of values

please help

Suppose you have 10 and 14 and 18. Should those all get merged together, even though 10 is more than 5 away from 18 ?

Also, what should the output look like?

Answer 1

[Matt J]

See the accumarray() command

[kash]

Matt can you please provide a example for above i went throygh documentation bu could not get any right opt for my question of using it

[kash]

I need to reduce those 7 set of values to around 4 or 5sets ,please can help me

[Matt J]

Give a small example of input and the desired output.

Answer 2

[Matt J]

HISTC may also be what you want, but it seems like you've already used a similar command to histogram the ABC values. If so, it's not clear what further reduction you're looking for.

[kash]

if there are 7 images or matrices, imagine we get 7 topics like this
img1:  80.1%,9.9%,10%
img2: 80%,10%,10%
img3: 79.5%,10%,10.5%
img4: 65%,20%,15%
img5: 67%,19%,14%
img6: 73%,17%,10%
img7: 72%,16%,12%

now we can club these probabilities to create topics for this example we can create 3 topics
img1,img2,img3 can be combined and we can give 1 topic for it
img 4,img 5 can be combined to form one topic
img6,img 7 can be combined to form one topic
therefore totally 3 topics

[Matt J]

Define a "topic". Also, give a quantitative input/output example (a small one) of the operation you want to perform

[kash]

now i want to combine images which are similiar or with a difference of + or - 5,after combining i will get 3 or 4 sets of values

the output will be for example

60.5%Green land 

25.5%Others 

14 %Others1..like these need 3 or 4 sets of values

[kash]

s it can be combine

[kash]

i have following values in command window as

33.2%Green land

26.1%Others

40.7%Others1

41.3%Green land

22.9%Others

35.7%Others1

25.3%Green land

8.5%Others

66.1%Others1

23.2%Green land

40.3%Others

36.5%Others1

35.5%Green land

35.5%Others

29.0%Others1

19.1%Green land

20.5%Others

60.3%Others1

now i want to combine images which are similiar or with a difference of + or - 5,after combining i will get 3 or 4 sets of values

the output will be for example

60.5%Green land

25.5%Others

14 %Others1..like these need 3 or 4 sets of values

[Walter Roberson]

If 10, 14, 18 should all be combined, then the implication is that all groups are potentially combined into a single group even though the top and bottom values might differ substantially. You would allow 1:5:36 to all combine into a single group.

[kash]

walter ten how to combine to get atlest 3 to 4 groups as i have posted

[Walter Roberson]

Your values might all be the same, making it impossible to split them into 3 to 4 groups.

Not enough of your values might be within 5 of each other in order to split into as few as 4 groups.

[Pat]

walter same values with difference of + or _ 5 can be made into groups

[Pat]

ok walter can we do in this way ,take means of all values so we get seven means values ,then find mean with greater difference and display those 3 values
