Hello,

i have a stuct which holds 12 signals. The signals are represented by frequency, power and a vector for each of the signals as seen in the following picture:

I have another matrix of the signals which passed through some model as seen in the follwoing picture:

I would like to merge the struct with the matrix, so that the struct will hold another column/new field where each struct row corresponts to each matrix row. How can I do this w/o for loop?

Thanks!

You cannot avoid a for-loop altogether, but you can avoid writing your own for-loop as follows:

tmp=num2cell(modelOutputSignal,2); %num2cell has a for-loop inside it.
[yourStruct(1:numel(tmp)).newfield]=deal(tmp{:});

Matt J ,

Another question.

When i have such struct:

How can I "cut" the 2 left columns "Inputrequency_MHz" and "InputPower_dBm" into some new struct?

say the structure is named s,

s.outputSignal = modelOutputSignal;

adds the matrix as an element to the structure. You can then reference a matrix element as s.outputSignal(rowNumber, columnNumber)

I get the following error:

Scalar structure required for this assignment.
