Calculate a matrix through a for loop

Hello,

I have the following code to which I am trying to find variable B. Veriable B is a matrix that will include the data in column 150.

for i=1:100
    A=users(:,i) % users is a matrix 1140X100 logical
    NonRev=(A==0)
    possRec=NonRev.*CloUserRat %CloUserRat is a matrix 1140X1
    [prices,ind]=sort(possRec)
    if (prices>0)
        B=ReMatrix(ind,150) %ReMatrix is a matrix 1140X837
    end
end

When I run the code in Workspace, the variable B is not submerged and in the command window displays the message that the vabiable B is not defined. your help is valuable.

stelios - B will only be defined if the prices > 0 condition is satisfied. Have you confirmed that this is ever true? Also is prices a scalar or an array? If an array, do you expect all elements to be greater than zero?

The prices are a 1140X1 double matrix as well as ind is a 1140X1 double matrix. The prices matrix has a column that is in ascending and contains zeros and some non-zero numbers. What I want to find in B is the non-zero numbers from matrix prices what values correspond to the matrix ind.

[Geoff Hayes]

yes but if The prices matrix has a column that is in ascending and contains zeros and some non-zero numbers then how will the condition prices>0 be satisfied (if there are non-zer numbers in prices)?

It is ok, I found and correted the error that was there. Thank you for your interest!!!
