I have a matrix eg [1,6,3], and i have a 31*1 cell array ,each element of cell is a matrix. My problem is i wants to extract matrix from the cell position {1*1},{6*1},{3*1} and to be stored all these in separate matrices.

I use the loops and values ​​but I can not seperate and store each iteration values ​​as matrices please help me for this problem

Cell Assigned_P = (31 * 1)

not clear illustrate with an example

i have a cell =C size (31/1) each element is a matrix of 3D point data. I have a matrix of X=[7, 6 ,5,8] values varying from 1-31.i want to extract element (7,1),(6,1),(5,1),(8,1) in the form of seperate matrix each.so that i can use this matrix values to plot a 3d graph.

As i use Q=C(X) gives me anothe cell with required data . If i use cell2mat() that gives me whole as on matrix .

but i wants to store each required cell in a seperate matrix that is used later for surface plot.

i use tha following code results a cell array

Adapted_P= P_giacitura(row)

Adapted_P =

4×1 cell array

{8532×8 double}

{2476×8 double}

{8532×8 double}

{8912×8 double}

please help me in this regard so far i am trying this,if i dont do this i dont even move single step ahed for my project.

thankig you

E.g., is this what you want?

c = your 31x1 cell array
v = your vector of indexes, e.g. [1,6,3]
result = c(v); % extract the cell elements according to the indexes in v

Not sure why you want the results in separate variables. It is much simpler to access the results as simply result{1}, result{2}, and result{3}, etc.

in my question the index vector is varied in between 1 and 31 .And eah element in cell is a matrix with lot of dat points.later i wants to use this information for the graph.All i want is if i give index vector as input ,i need out as index position matices in the cell automatically.I try to use For clearloop but i is not storing the matrices separately.

Thanks for the response.I hope with this it is

hi sir thank you it works for my code.And only remaining thing is i wants to draw a 3D graph based on this cell matrices.The code gives me 3*1 cell array.each one cell shoul give one graph.

thank you
