I am trying to implement matlab code in hdl using hdl coder.But iam getting errors like variable not initialized during fixed point conversion.How to resolve .Pls help

function [o]=fyp(a) load('100m'); a=val(1,:); subplot(3,2,1); plot(a); title('original ECG signal') b1=strel('disk',3); b2=strel('disk',4); b3=strel('disk',5); out1=imbothat(a,b1); out2=imtophat(a,b1); out3=imopen(a,b1); out4=imclose(a,b1); o1=(imsubtract(out1,out2))/2; o2=(imadd(out3,out4))/2; o=(imadd(o1,o2)); subplot(3,2,2); plot(o); title('After 1M filtering'); out11=imbothat(out1,b2); out21=imtophat(out2,b2); out31=imopen(out3,b2); out41=imclose(out4,b2); o11=(imsubtract(out11,out21))/2; o21=(imadd(out31,out41))/2; o1=(imadd(o11,o21))/2; % subplot(3,2,3); % plot((o1+(o/2))); % title('After 2M filtering'); out12=imbothat(out11,b3); out22=imtophat(out21,b3); out32=imopen(out31,b3); out42=imclose(out41,b3); o12=(imsubtract(out12,out22))/2; o22=(imadd(out32,out42))/2; o2=(imadd(o12,o22))/4; subplot(3,2,3); plot(o2+(o1/2)+(o/4)); y=o2+(o1/2)+(o/4); title('After 3M filtering'); m=0:3599; for m=2:length(y)-1 ys(m)=abs(y(m-1)+y(m)); end subplot(3,2,4); plot(ys) title('QRS') end

please follow the steps in this getting started tutorial

https://www.mathworks.com/help/hdlcoder/examples/getting-started-with-matlab-to-hdl-workflow.html

the first step is to break the code into design and testbench files.
