Hello,

My background in in RF but my matlab skills are limited. I have an excel sheet with data. I want to

1) Import the sheet into matlab

2) Plot Column I vs H

3) Plot Column D,E,F on 3d plot/surface plot/contour

4) Plot Columns I+jH on smith chart

I have made just a little progress. Please help me with #3 and #4.

Thanks. Please see the attachment of excel sheet. Please see my code below :

dataset = xlsread('DataAnalysis.xlsx','Sheet1');

x = dataset(:,2);

y = dataset(:,1);

figure(1);

plot(x,y,'r.-');

xlabel('R in ohm');

ylabel('X in ohm');

title('Resistance vs Reactance');

grid;

figure(2);

sm1 = smithplot(dataset);
