MATLAB: How to shift a vector using ‘for’ loop

MATLAB

Dear members

Firstly,I have many vectors for example (V1, V2, V3, V4 …) of M length.

How can I use 'for' loop to obtain firstly [V1 V2] then [V2 V3] then [V3 V4], [V4 V5] … etc. It means I shift the previous vector each time.

Thank you.

Store all of the vectors in one cell array (which they should be anyway):

C = {V1, V2, V3, V4 ...};

then all you need is this loop:

for k = 2:numel(C)
    [C{k-1},C{k}]
end

or even just this:

for k = 2:numel(C)
    [C{k-1:k}] % comma-separated list and concatenation
end

MATLAB: How to define an arbitrary constant for equations

If you are talking about making an assumption, you can do it as follows:

v1=6;
v3=18;
syms v2 v4 v5 v6
eqn1= -v4+v5==-v3;
eqn2= -v2+v6==v3;
eqn3= -v5-v6==-v1;
assume(v6~=0)
[v2 v4 v5 v6]=solve(eqn1, eqn2, eqn3);
[v2 v4 v5 v6]

MATLAB: How to explicitly change the colors of the bars in a stacked bar graph

You can use the Color Data (CData) property for bar graph released in R2017b.

You can change the color for a particular bar by setting the FaceColor property to 'flat'. Then, change the corresponding row in the CData matrix to the new RGB triplet. Here is the link for the CData property in bar graph:

https://www.mathworks.com/help/matlab/ref/bar.html#input_argument_namevalue_d119e63137

For example,

a = [1,3,6;2,5,6;8,2,1];
H=bar(a, 'stacked');
colorSet = [];
for i = 1:3
    myColors = round(rand(3,3),1);
    colorSet = [colorSet myColors];
    H(i).FaceColor = 'flat';
    H(i).CData = myColors;
 end
This will display the stacked bar plot with different colors.
